Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing and/or processing a metal plate (especially a steel plate) composed of a metal material, wherein the metal plate is heated from a continuous prayer device Feeding into the plate library, the cooled metal plate enters the heating furnace from the 哕纟4 low a 板材 板材 plate library and is heated in the heating furnace, and the heated metal plate enters the strip hot rolling mill from the heating furnace and is The strip hot rolling mill is subjected to rolling treatment. 2 invention also relates to a method for manufacturing and/or processing a metal plate or a metal strip (especially a steel plate or a steel strip) composed of a metal material, in which a τ 5 hai metal sheet is fed into a heating furnace and is heated in the furnace The heated metal plate is fed into the hot strip mill from the heating furnace, subjected to rolling treatment in the hot strip mill and rolled into a metal coil. The invention further relates to an apparatus for manufacturing and/or processing metal sheets or metal strips composed of a metallic material. [Prior Art] In the process of cooling liquid steel from about 157 (TC to 12 〇 (the middle temperature of rc, liquid steel will lose about I" kWh/t enthalpy when it comes out of continuous casting equipment. This heat It is often dissipated into the surrounding environment (air and cooling water) without using it. In the traditional strip hot rolling equipment, after the casting process, the residual heat of the metal sheet is usually used or the metal sheet is directly rolled. The metal plate is hot-packed with a heating furnace, thereby saving a lot of heat energy. It is mentioned that the hot-casting or direct charging is that the continuous casting equipment and the metal plate heating furnace are arranged close to each other in space. However, the previous equipment is not always This condition can be met. For reasons such as logistics and surface inspection 'rolling procedure design, only Qa can be processed directly or in a hot state. Therefore, in the case of 201036733, the metal will be finished after the casting process. The board is placed in a ventilated place for cooling, and the metal sheets are stacked into a stack and then further transported to the next processing point. The residual heat in the wound metal coil is also the same. Residual heat is often dissipated in the air in the coil library. Energy-intensive industrial sectors such as the metal industry, cement industry or glass industry are increasingly using waste heat and process heat to convert thermal energy into electrical energy. In the field of steel, there is also a corresponding solution proposed in WO 2008/075870 A1: waste heat generated in a fluidized bed reactor due to reduction ruthenium in the production process of liquid iron to produce high pressure steam, followed by high pressure The steam-driven turbine is used to generate electricity. DE 26 22 722 C3 discloses a device for cooling a hot steel plate immediately following the previous rolling process. In this device, the steel plate is erected between several vertically positioned columns arranged side by side. The heat is arranged between the positioning columns and is absorbed by the cooling wall of the tube bundle of cooling water for the manufacture of steam. Ο EP 〇 027 787 B1 describes a method of casting by continuous casting using air in a cooling chamber. The metal plate acquires a device capable of sensing heat, wherein a fan is used to directly contact the air with the surface of the metal plate. The air heated in this manner is subsequently The cooling chamber is used as a heating medium, in particular, as a circulating medium for entering a thermodynamic cycle. ',,; and using the heat of a metal plate or a metal coil to obtain electrical energy often requires a relatively complicated equipment configuration. In view of this, it is an object of the present invention to provide a method and apparatus of the type 201036733 of the opening paragraph, whereby both can also be beneficially utilized for energy present in a metal sheet or metal coil, but without the need for complicated large-scale equipment. According to the method, the solution to this object is characterized in that heat is taken from the metal plate by a gas flow in a heat exchanger disposed between the continuous casting device and the plate stock, thereby The gas stream is heated, and the heated gas stream is directed to a heating furnace, specifically for heating the furnace of the metal sheet, and is fed to the furnace as a furnace air. Wherein the metal plate preferably enters the heat exchanger at a temperature between 8 ° C and 10 ° C and is cooled to 200 ° in the heat exchanger before leaving the heat exchanger The temperature between C and 400 ° c. The solution to the present invention when applied to a metal coil is as follows: in a heat exchanger disposed behind the strip hot milk machine, heat is taken from the hot metal coil by an air flow 'by heating the air flow' The heated gas stream is directed to a furnace which is specifically directed to heat the metal sheet or the metal strip and is fed to the furnace as a furnace air. Wherein the metal roll is preferably between 450. (: with 550. (: the temperature enters the heat exchanger' and is cooled in the heat exchanger to between 150 ° C and 250 before leaving the heat exchanger. (: between the temperature. Feed into the furnace The gas flow rate is preferably such that the fuel (especially the gas) added to the air can be completely (stoichiometrically) burned in the furnace. The second heat exchange can be performed before the far gas stream is sent to the furnace. The air is further heated by the exhaust gas of the heating furnace to further improve energy efficiency. According to one embodiment of the invention, the apparatus for manufacturing and/or processing a metal plate composed of a metal material comprises a continuous casting device, along the conveyance 201036733 A direction plate is disposed behind the continuous casting apparatus for storing a sheet metal plate for cooling the metal sheet, a heating furnace for heating the metal sheet, and a strip hot rolling mill disposed behind the heating furnace. According to the present invention, the continuous casting equipment and the sheet metal library Arranged between the heat exchanger for obtaining heat from the metal sheet, wherein the heat exchanger is connected to the heating furnace by means of an air conveying device (especially an air duct) (especially for heating the metal sheet) Furnace) so as to heat from the gas stream into the preheated furnace.

Wherein the heat exchanger is connected to the heating furnace (especially the heating furnace for heating the metal sheet) by means of an air conveying device (especially an air duct) to feed the preheating gas stream from the heat exchanger to the heating furnace. It is used to heat metal to be processed in heating metallurgical equipment. This concept also includes components such as the 'burner flow cell heating stage. Any airflow is preferably arranged in the material and auxiliary material at least - 'air delivery device (especially heating furnace) means the material in the metallurgical equipment; but this concept also includes other materials (acid washing liquid) The heating device for heating the heating of the special equipment for heating the metallurgical equipment or the heating of the burner is heated by the hot material or processing medium and the device heated in the heat exchanger. Conveying device (especially air duct) A fan for rotating heated air. In addition, 201036733 refers to an air duct) + at least one air filter can also be arranged. The function of the air filter is to prevent particles from being transferred to the burner in the furnace. The fan feeds the air required for the complete combustion of the gas in the furnace (stoichiometric mixture) into the furnace. That is, the present invention uses a metal plate or a metal coil as an energy source to heat the heating metal of the furnace. The process of the plate is more economical. The temperature of the metal plate used is usually about 900 ° C; the metal roll is usually about 5 〇〇 ac. When applying the present invention, Whether the metal sheet or the metal coil is cooled to ambient temperature without any use, energy loss can be avoided. Before entering the strip hot rolling mill, the metal sheet must be heated to about 1 〇 5 〇. 匸 to 1100 The temperature of C can greatly reduce the primary energy required for this process by the application of the present invention. Gas is generally used as a primary energy source, but in the case of applying the present invention, the conventional dosage will no longer be required. It is also beneficial to use the waste gas to make steam and use the steam to drive the steam turbine to generate electricity. It should be noted here that although the concept of "(empty) gas flow" is used (ie, it needs to be heated in the heat exchanger to utilize it). The heat of the present invention achieves the (empty) gas flow of the heating process of the present invention, but the present invention also includes the use of other gases without the use of (pure) air. The reason for this is that one of the air is not allowed to be considered. Avoid other ingredients (solid or liquid particles, such as dust and condensate), on the other hand, use other flammable This means that the present invention can be achieved by using a conventional gaseous medium as described above, even if air is not used. The invention also relates to a metal sheet 201036733 or a metal coil (especially a steel sheet) made of a metal material. Or heat in a steel strip coil to heat the medium (especially air). In order to utilize the heat in the metal sheet or metal coil, an efficient working heat exchanger must be used. The heat exchanger must be self-contained. The heat is taken from the metal sheet or metal coil and transferred to the medium (usually air). The heated medium can then be fully utilized in the above-described conventional methods and apparatus. Accordingly, another aspect of the present invention The object is to provide a device for heating a medium (especially air) by using heat in a metal plate or a metal coil (especially a steel plate or a steel coil) made of a metal material, which can be used in a metal plate or a metal coil. A particularly efficient heat exchange between the media is achieved. This allows optimum use of the thermal energy contained in hot metal sheets or metal coils. A solution to this object is characterized in that the device has: an insulating housing, at least one inlet for a hot metal plate or a metal coil, at least one for the exit of the cooled metal sheet or metal coil, at least one fresh "Quality guide (especially a fresh air duct) that extends from the outside (specifically from the surrounding environment) into the housing, at least one medium conduit (especially an air duct) through which the medium conduit The heated medium can be output from the housing, and at least two enamel ports (especially air passages) stacked one above the other can be transported along the two media channels. Preferably, a lifting device is arranged in the inlet area, by which the metal plate or metal coil can be raised to the height of the air passage or lowered to the inlet height. Lifting equipment can also be arranged in the exit area, and the lifting or lowering can be used to lift the metal plate or metal coil to the height of the air passage or to the height of the outlet. Preferably, the lifting device can also be implemented as a long-term translation of a metal plate or a metal roll into the medium in a horizontal direction: a channel: a zone and a domain (inside) outlet, within the domain), the metal plate is removed or extracted from the media channel in a horizontal direction. Or metal coils. Greedy plate In addition, at least one of the interior of the housing can be arranged to generate an air flow within the housing. The ventilator, through the ventilator inlet and outlet, can communicate with the interior of the housing by a gate, respectively. From the top view of the device, the air passage preferably extends from the population area to the exit area. Among them, the air passages are preferably horizontally distributed. However, the invention-specific embodiment of the air passage can also be extended with the horizontal clamp - the sharp angle descends toward the outlet. The air passages stacked one above the other are preferably separated from each other by the air guide. Finally, the air passage may have a guide or roller for moving the pallet to which the metal plates or metal coils may be attached. Here, the metal plate or the metal coil is also used as an energy source to heat the medium, so that the process of heating the metal plate of the heating furnace is more economical. The temperature of the hot metal plate to be used is usually about 9 GGt: the metal roll is often used. c or so. That is, if a heat exchanger is proposed in accordance with the present invention, the thermal energy of the metal plate or the metal coil can be utilized to make it a cooling temperature lower than the temperature level of the prior art (about 200 C to 30 (TC). This avoids the loss of energy. It is preferred to use air as the medium, but the invention may in principle also use other media. The figures show an embodiment of the invention. 10 201036733 [Embodiment] FIG. A schematic diagram of an apparatus for processing a metal sheet into a metal strip. The drawing is only schematically illustrated for the continuous casting apparatus 1. The continuous transfer apparatus processes the liquid metal into a metal sheet in a conventional manner. The metal sheets such as S Hai are always stored in the sheet metal stock 2. The metal sheet transporting rolls 10 for transport are provided, and the metal sheets are refrigerated in the sheet stock 2 before being subjected to subsequent processing. After exiting the continuous casting apparatus i, the metal sheet still has a temperature in the range of about 1 〇〇〇 ° C.

Then the heated metal sheet is fed into the strip hot rolling. The machine 4 is also subjected to rolling treatment here. In order to convey the metal plate in the furnace, the heating furnace must be designed, for example, as a walking beam type furnace or a propelling type heating furnace. 4 The rolled metal strip is rolled into a metal roll and transported away therefrom by a metal roll output device. The point is that the metal sheet must be transferred to the sheet stock 2 from the continuous casting equipment. The residual heat of the metal plate is used to preheat the air of the heating furnace. For this purpose, there is a change, a device 5 (hot plate library), and the metal plate enters the heat exchanger and releases a part of heat, which is entered as heated air. The furnace 3 is heated. For this purpose, the heat exchanger 5 is connected to the heating furnace via an air delivery device 7 (air duct). In order to clarify the flow of air from the heat exchanger 5 to the furnace 3, the air delivery lag 7 is arranged Fan 8.

The inside of the furnace itself is heated by gas combustion. Its A' is completely burned by the air delivery device in a quantity determined by the fan 8. The waste gas of the potting furnace 3 can also be fully utilized, for example, to drive the turbine 13 by manufacturing the base π. Figure 2 shows an apparatus for processing a metal sheet into a metal strip. Here, the two-plate is passed to the heating furnace 3 by the metal plate transfer roller 1 and heated therein. Then, it is rolled into a metal in the tape hot-rolling machine 4, and the metal tape is then wound into a metal roll. The metal coil leaves the strip hot rolling mill 4 at a temperature of approximately 50 (rc. This heat energy will be utilized as follows without dissipating in the surrounding environment: hot metal coils after the strip hot rolling mill 4 Entering the heat exchanger 5, (hot coil library) and transferring its heat to the supply air stream here. The heated air flow is transported by the air duct 7 to the heating device (for example, the heating furnace W and is guided 12 201036733忒 Heating equipment.

Therefore, by the air circulation density, the number of the metal plates 22 in the heat exchanger $ and the size of the heat exchanger Control can be optimized to minimize input costs and operating costs. Figure 7 and Figure 7 show, in schematic form, a preferred embodiment of the heat exchanger 5 for a metal coil of the present invention. The hot metal coil enters the heat exchanger 5' at the metal coil inlet 29 and the cooled metal coil 31 exits the heat exchanger at the metal coil outlet 30. The metal coil population 29 and the gold Htb cr % are provided with gates not shown in the drawings. Fresh air enters the heat exchange S 5' via the fresh air duct 24; the discharge of the heated air is achieved by the air duct 7. As shown in Fig. 7, the metal coil 31 to be cooled is still stacked in a plurality of layers. Further, the metal coil 31 moves slowly from left to right. An air flow is generated by the ventilator 23 in the apparatus equipped with the metal coil 3 to ensure that the metal coil 3 1 efficiently transfers its heat to the air inside the heat exchanger 5. Each layer (four layers are still shown here as shown in Figures 6 and 7) constitutes a self-contained air passage for the 15 201036733 13 gas guide plate 25. These wire guides absorb the radiant heat of the metal roll 31 and transfer it to the circulating air.

Feng can set the skylight on the top of the heat exchange state, and the news will happen, and the visit will be opened, and the 访天® will open. If this measure is not enough to eliminate the electricity _ from the emergency electricity line „. Wit 1 The solution proposed by the invention is applicable to any type of hot machine, especially for flat steel, steel and pipe. /,, Μ: Information can be Illustratively, the annual production of the i·-furnace strip hot rolling mill obtained by applying the invention to a metal sheet is, for example, five million steel. The energy of the metal 16 201036733 sheet is utilized, wherein the metal sheet is self-contained. c is cooled to about 300 ° C. This corresponds to about 420 kWh of heat. The forced convection through the heat exchanger (hot coil library) and the heat in the heat exchanger in front of the furnace The exchange process can utilize about 14 kWh of this. This is roughly equivalent to 2% of the energy of the metal plate used. The following information can demonstrate the effectiveness of the invention applied to the metal coil: The annual output of the three-furnace strip hot rolling mill is, for example, five million tons of steel. The energy of the metal coil is utilized, wherein the metal coil is cooled from about 5 ° C to ° c. This is equivalent to about 200,000,000 kwh of heat. Through the heat exchanger (hot coil library) The forced convection and the heat exchange process in the heat exchanger in front of the furnace can utilize about 70000000 kwh, which is roughly equivalent to the i 〇% of the energy of the metal plate used. Another important advantage is that The application of the concept of invention can also achieve C Ο 2 emission reduction: In the case of an annual output of 5 million tons, by adopting heat exchange measures for metal plates, c〇2 emission reductions can reach about 30,000 tons; The metal coil adopts heat exchange measures', then the C〇2 emission reduction amount can reach up to 5,000 tons. Figures 8 and 9 show a heat exchanger type device 1〇1. The heat exchanger 101 is used for the metal coil 102. The heat exchanger 101 has an insulated housing 1〇3. The hot metal coil enters the heat exchanger 1 at the inlet i 04 for the metal coil 102 (H, the metal coil 102 through the cold portion is used for the exit of the metal coil The heat exchanger 101 is left at a distance of 1. The inlet 104 and the outlet 105 are provided with a gate not shown in the drawing. The fresh air enters the heat exchanger via the fresh air conduit 106: 1 plus 17 201036733 hot air Discharge is achieved by air duct 〇 7. As shown in Figure 8 and Figure 9, to be cold The metal 4 1〇2 is stacked up and down into a plurality of layers. Further, the 'metal coil 1〇2 is slowly moved from left to right. In the heat exchanger 101 equipped with the metal coil (10), the airflow 116' is generated by the two ventilators 114 and ιΐ5. Ensure that the metal coil 102 effectively transfers its heat to the heat exchanger (8): empty milk. This means that the 'ventilators U4, 115 can improve the heat transfer efficiency by forced convection. By the fan 114, the heat can be exchanged The wind speed of the highest f 1〇_ is generated in the device i. Thereby, the metal coil can have, for example, 8 hours of residence time for the heat exchange process. As shown in Fig. 8 and Fig. 9, four layers are provided here. Forming one of its own (10)...^(1) These air passages (10) (10), Volume 2: are defined by air guides 117. The air guide 117 absorbs the heat of the roll of the metal coil 2 and transfers it to the circulating air. The second lifting device 2 is arranged in the heat exchanger, and the lifting device in the left side region of (8) is raised to the placement position of each layer, and is inserted into the air passages 108, (10), 110 from the left 6 117 boundary.

Lifting 6 and (lifting) 113 are unloaded and passed. Due to the heat exchanger 1〇1, the output of the metal coil T1 is loaded into the production roll and on the right side of the heat exchanger (ie, from: the genus is favorable for cooling) The mode forms a temperature drop from left to right, ie from the entry side towards the wheel exit side. A plurality of independent air circulation zones are constructed in the heat exchanger UH (for example, this is also beneficial. If so, then 18 201036733 air is in the first ring zone. (left side) The degree of heating is higher than that of the inter- or right-hand side as shown in Figures 8 and 9, gold; the left-to-right transfer is carried out on the guide rail or roll "118 (see ® 9), where the tray U9 can be used. When moving up, the metal coils are fixed on the trays to prevent damage. When the airflow 116 (air circulation) generated by the ventilator m, 115 is stopped due to power failure, the heat exchanger 1〇1 is overheated. For this purpose, a skylight can be placed on the top of the heat exchanger, and when the above occurs, the skylight is opened. If this measure is not enough to eliminate the hidden danger, it must be ventilated by the emergency power supply. The figure shows the heat exchanger 101 in schematic form. An alternative embodiment of the embodiment shown in Figure 9. The difference from the solution shown in Figure 9 is mainly in that the guide rail or drum 118 and the air passages 1〇8, 1〇9, 11〇, 111 here. (The other air channel is also shown here) is not horizontal The cloth is inclined toward the horizontal line by an angle α (the angle is about 15). Thereby, each tray 11 9 can be slid toward the outlet 1 〇 5 without an independent driving device 'at the end of the air passage by the elevator 113 The tray and the fully cooled metal coil on the tray are removed. Figures 11 and 12 show a schematic diagram of a heat exchanger 11 for a metal plate 22. The hot metal plate 102 is used at the entrance of the metal plate 1〇4 Entering the heat exchanger 101, the cooled metal plate 1〇2 leaves the heat exchanger 1〇1 at the outlet 105. The gates of the inlet 104 and the outlet 105 are still provided with the gates not shown in the drawing. 11 and FIG. 12, the metal plate 102 to be cooled is still stacked in a plurality of layers (indicated by V in the vertical direction). Further, the metal plate 102 is still slowly left to right from the perspective of the diagrams of FIG. Movement. Airflow 116 is generated by ventilator 114 in heat exchanger 101 containing metal 19 201036733 plate 102 to ensure that metal plate 102 effectively transfers its heat to the air within heat exchanger 101. As shown in FIGS. 11 and 12, four layers are provided here to constitute an air guide plate 117. Self-contained air passages 1〇8, 1〇9, ιι〇, (1). The metal plate 102 is still lifted in the left side area of the heat exchanger 1〇1 and lifted to the placement position of each layer, and inserted into the ... The air passages are -, and the metal plates are slowly conveyed with the right side. The cooled metal plates 102 are unloaded by the elevator 113 in the right region of the heat exchanger 101 and transferred to the outlet 105. The metal plates 102 are mounted on the left side and the metal plates are output on the right side of the heat exchanger as shown in FIGS. 9 and 12, which can be formed from the left to the right in a cooling manner (ie, from the entry side to the wheel exit side). The temperature drops. In order to achieve precise control of the air flow of the & 11 101, both the fresh air guide 1 〇 6 and the air duct i 〇 7 are equipped with a throttle valve. Rong also needs a certain amount of energy when working in the fan m Xiao 115. The size of the heat exchanger will also have a corresponding cost, so by the air circulation density, the metal coil or the metal plate in the heat exchanger 〇11 The quantity and heat exchanger size are controlled to optimize the investment and operating costs as much as possible.
