Definitions
- the invention relates to tapping channels for the removal of iron and metal melts and the liquid slag from metallurgical containers, in particular blast furnace and furnace,
- one or more taphole channels are arranged in the lower part of the furnace, which are hm practicgeschreibt through the usually several meters thick refractory lining.
- the internal pressure of the blast furnace or melting furnace must be overcome. Due to the high temperatures, the stuffing material hardens and forms a sealing plug.
- the cured stuffing is pierced until it reaches the melt inside the blast furnace, so that the melt stream starts again.
- the fungus formed by the stuffing compound on the refractory lining of the inner wall of the blast furnace has the task, the wear, which is caused by the outflowing melt and especially by the slag at the inlet opening of the taphole channel, to keep away from the blast furnace inner wall.
- the hardened stuffing mass is exposed to chemical and abrasive wear during the tapping operation, so that the taphole channel widens in an uncontrollable, undesired manner.
- a method for forming a drainage channel of a taphole on a shaft furnace in which a refractory tube pushed onto a tapping rod is introduced axially m a stuffing mass injected into the tapping hole.
- a refractory tube pushed onto a tapping rod is introduced axially m a stuffing mass injected into the tapping hole.
- substantially only the front end of the tube is inserted into the stuffing mass, so that a major part of the tube protrudes with respect to the wall of the shaft furnace.
- the pipe is locked in the extension of the tap hole and for opening the tap hole, the tap bar is pulled out of the hardened stuffing material through the pipe, so that the drainage channel of the tap hole is formed inside the wall of the shaft furnace directly in the stuffing box and the drainage channel is outside the wall of the stuffing box Shaft furnace is extended through the pipe.
- the invention has for its object to develop a tapping channel for the discharge of iron and metal melts and the liquid slag from metallurgical Behaltern, in particular blast furnace and furnace, compared to an abrasive and chemical wear caused by the emerging from the furnace melt and Slag stream is effected, has a high resistance and can be renewed with respect to the known embodiments of Stichlochkanalen at regular intervals with a much reduced time and cost.
- the dependent claims contain advantageous and expedient developments of the tapping channel.
- the erfmdungsgemaiche tapping channel for blast furnace and furnace is characterized by the following advantages:
- Fig. 1 is a longitudinal sectional view of the tapping channel
- FIGS. 2a is a fragmentary, enlarged, and 2b perspective view of an inner pipe section of the tapping channel composed of pipe jacket segments and a perspective, enlarged view of a pipe jacket segment,
- 3 is a longitudinal sectional view of a machine for inserting the inner pipe sections before inserting an inner pipe section into the outer pipe of the tapping channel of a blast furnace
- 4 shows a cross-sectional view of the tapping channel equipped with a device for controlling the flow velocity and for braking a melt stream
- Fig. 5 is a longitudinal sectional view of a equipped with a Kuhlvorraum tapping channel
- Fig. 6 is a longitudinal sectional view of another embodiment of the tapping channel with an outer tube and an inner tube with a profiled inner wall.
- the m Figure 1 illustrated tapping channel 1 of a blast furnace 2 is formed by an outer tube 3 and a m this axially displaceable inner tube 4, wherein the outer tube 3 is firmly connected by Vermortelung with the refractory lining 5 of the blast furnace 2.
- Both tubes 3, 4 are made of a high-strength, preferably ceramic material or carbon stone and the material of the inner tube 4, which serves to stop the abrasive and chemical wear by the outflowing pig iron and the effluent slag, is additionally resistant to abrasive and chemical wear ,
- the inner tube 4 consists of pipe sections 6, which are replaced to compensate for the occurring abrasive and chemical wear at certain time intervals by new pipe sections 6a, wherein the new pipe sections ⁇ a through the outlet opening 7 of the tapping channel 1 against the direction of flow a of the blast furnace 2 emerging Melted stream 8 inserted into the outer tube 3 while simultaneously worn pipe sections 6b are pushed through the Emlaufo réelle 9 of the tapping channel 1 from the outer tube 3 out in.
- this m is approximately flush with the blast furnace outer wall 10 from.
- This inner pipe section 6b assumes the function of the so-called mushroom formed by the stuffing compound on the inside of the lining of a blast furnace in the conventional tapping process.
- the time interval of the insertion of new pipe sections 6a is chosen so that destruction of the inner pipe sections 6 is avoided and thereby contact of the melt and the slag with the outer tube 3 is excluded.
- a layer 14 of a lubricant preferably on a mineral basis, which develops its full lubricity at the high temperatures of the outflowing iron and the effluent slag and only at temperatures significantly below those of liquid metal, stiffens.
- the pig iron slag mixture and especially by the aggressively abrasive acting slag at the emiration of the tapping channel and over the entire length of the tapping channel occurring wear is absorbed by the inner tube 4. From the outer tube 3, any wear is kept away, so that the tapping channel 1 maintains its shape and is not widened.
- the inner pipe sections 6 are significantly more resistant to wear than the conventional, during the tapping solidified stuffing. In the selection of materials, these pipe sections can be designed exclusively with the aim of the highest possible wear resistance, while the stuffing also needs to meet other requirements such as Piastizitat during the stuffing process and drillability for re-initiating the subsequent Abstichvorgangs.
- the highly wear-resistant inner tube sections 6 will be subject to wear over time despite a significantly lower wear rate. It is ensured by the arrangement of the outer tube 3, lubricant 14 and inner tube sections 6, that when einanddem wear the inner tube sections 6 m pushed into the blast furnace 2 and can be replaced by inner tube sections before destruction occur.
- the material of the inner pipe sections is chosen so that they decay after prolonged residence time in the melt inside the blast furnace by the local flow movements and vortices over time and their remnants can be discharged at later taps through the tapping channel.
- shut-off valves and closing flaps as well as a deliberately induced solidification of the melt in the tapping channel for the termination of the tapping process and a later re-melting of the solidified melt for a new tapping process.
- the inner tube sections 6 consist of rod-shaped tube jacket segments 15 arranged axially next to one another, so that the outer tube 3 of the tapping channel 1 and the tapping channel 1 do not coincide with the inner tube section 6 formed by the tubular jacket segments 15 , the tube shell segments 15 are positively connected to each other.
- the rod-shaped tube shell segments 15 on the outer circumference on one side each have a longitudinal web 16 and on the opposite side of the long web 16 adapted paragraph 17, such that during assembly of the pipe sections 6 of the inner tube 4 of the long web 16 of a tube jacket segment 15 with the paragraph 17th the adjacent tubular jacket segment 15 xn engaged.
- the tube shell segments have lost a substantial portion of their original thickness m the result of Abrasionsverschl devises at the taps for a long period when inserted into the interior of the blast furnace, they break at the inlet side of the tapping channel on the inner wall of the blast furnace by the flow energy and vortex formation during inflow of iron and slag in the tapping canal.
- FIG. 3 shows a machine 18 for inserting inner tube sections ⁇ a in the outer tube 3 of the tapping channel 1 of the blast furnace 2.
- the machine 18 On a rotatable and pivotable boom 19, the machine 18 is mounted, by means of which new inner tube sections 6a m the outer tube 3 of the tapping channel 1 is inserted m can be nachgeschoben the tapping channel.
- the tapping channel 1 is first closed once by a plug 20, which also serves as a guide for the introduced and nachzuschiebenden new pipe section 6a. After closing the tapping channel 1 push the piston rods 21 of the lifting cylinder 22 of the machine 18, the new pipe section ⁇ a m the outer tube 3 into it. This process is best done when the tapping is completed and the tapping channel 1 must be closed.
- the tapping channel 1 can be filled with conventional stuffing material, a Powder cartridge are used or other methods for tilling the tapping channel can be used.
- FIG 4 illustrates a tapping channel 1, which is equipped with a device 23 for controlling the flow rate and for braking and stopping a Mchtferromagnetician melt stream 8.
- the control device 23 has a core 25 which is formed as a double with two yokes 26, 27, on which four electric induction coils 28-31 are arranged.
- the core 25 has two poles 32, 33, which are arranged around the tapping channel 1.
- the induction coils 28-31 generate a magnetic field 34, which acts on the melt stream 8 in the tapping channel 1 via the narrow gaps 35 between the poles 32, 33 and the outer tube 3, the outer tube and the inner tube sections 6, such that m the melt stream.
- Eddy currents are generated, whereby forces are generated by the interaction of magnetic field and eddy currents, which are opposite to the flow direction a of the melt stream 8 and decelerate this. Both magnetic fields with the same polarity and alternating magnetic fields can be used.
- control device can reach the procedural advantage that the melt flow must be interrupted only when new inner pipe sections 6a must be inserted and pushed into the outer tube 3 of the tapping channel 1.
- the tapping channel 1 is equipped with a Kuhlvorraum 36 in the form of rohrfor ⁇ ugen Kuhlzin 37, over the entire length of the tapping channel 1 away or - as in this exemplary embodiment - surround the tapping channel 1 over a partial length and are arranged as close to the outer tube 3 , Melt streams 8 through 4 strongly braked after a tapping operation on a blast furnace under the Kuhlmann the Kuhlstoffs flowing through the Kuhi to 37, are solidified, so that in the outlet region of the tapping channel 1, a sufficiently strong sealing plug 38 is formed , By means of the electric induction coil system according to FIG.
- the sealing plug 38 of solidified melt can be remelted on its outer peripheral surface in contact with the inner pipe sections 6, so that the plug under the effect of the internal pressure of the Blast furnace from the tapping channel is printed out and a new tapping process can be initiated.
- the Kuhlvorgang can also be controlled so sensitive that only in the outer flow region of the melt stream directly to the inner pipe sections, a solidification or extremely kohlmanniger state of Schn ⁇ elzestroms is brought about shortly before the solidification point, so that an inner lining is produced on the inner wall of the inner pipe sections. In this way, the entire or at least the major part of the wear is kept away from the inner pipe sections during the tapping process.
- the ⁇ bstichkanal 39 according to Figure 6 is formed by an outer tube 3 and an inner tube 4, which consists of pipe sections 6, the inner walls 40 are formed as groynes 41, such that there is a series arrangement of groynes 41, the openings 42 in the flow direction a the melt stream 8.
- the series arrangement of the groynes 41 causes the flow velocity of the Schinelzestroms 8 on the inner walls 40 of the inner tube sections 6 relative to the Flow rate of the central melt stream is greatly slowed down and thereby the Abrasionsverschl redesign the inner pipe sections 6 is reduced.
