Definitions
- the invention relates to a device and a method for flexibly influencing the process control, in particular temperature control, of a metal product passed along a single passage line by means of at least two adjacent segments.
- the heat treatment can be heating, holding, cooling or even a
- heat treatment lines are usually designed and built up optimized for a specific metal product or a material group of metal products.
- a change in temperature control for example targeted cooling within a holding zone of a furnace, can only be implemented with difficulty in an existing heat treatment line, since furnaces usually react very slowly to changed temperature specifications.
- a change in temperature control can therefore only be carried out with a corresponding delay or downtime in production.
- Gas changes are also very time-consuming, especially in the case of large furnace segments, since appropriate purging times must be observed for safety reasons.
- a fundamental exchange of a heating method for example a natural gas-fired furnace for inductive heating, is not possible.
- Such segments can also be exchanged for maintenance purposes only possible if production is interrupted or production options are restricted.
- the object of the invention is therefore to develop a known heat treatment line in such a way that the process control, in particular temperature control, can be adapted more flexibly to different metal products and / or production conditions.
- the process control in particular temperature control, can be adapted more flexibly to different metal products and / or production conditions.
- the object of the invention is achieved with a device with the features of claim 1 and a method with the features of claim 18.
- the process control in particular temperature control, of a metal product passed through along a single flow line, in particular one
- Slab thin slab or a pre-rolled hot strip
- at least one segment being exchangeable for another segment by means of a transport process through a transport device having a drive unit.
- At least one segment is open as a furnace, encapsulated transport route
- Transport path and / or cooling path formed and a further furnace segment can be positioned next to a first furnace segment.
- a coherent work process in the sense of the invention can also consist of a large number of individual work steps. These work steps are carried out one after the other or at the same time without any significant delay.
- a drive unit can be a linear drive as well be a rotary drive. In the context of the invention, the drive can preferably be electrical, pneumatic or hydraulic. The drive unit can be arranged externally and only act on the segment or be arranged on the segment.
- the mutually interchangeable segments are arranged on a common support structure, preferably rails and / or preferably transversely and / or parallel to the line of passage of the adjacent segment.
- Process management in the sense of the invention can also include the acquisition of process data and / or product data for controlling or regulating the device and / or for storage in a higher-level data processing system.
- An exchange of a segment for another segment for maintenance purposes is also understood according to the invention as process management.
- one segment can be exchanged for another segment at the same time by the transport device by means of a transport process.
- simultaneous means that when one segment is moved out of the flow line, another is moved synchronously into the flow line.
- the segments are preferably movably and / or detachably attached to the supporting structure.
- the segments on the supporting structure can be exchanged and, if the product to be manufactured is fundamentally changed, they can easily be replaced by other types of segments and brought into the throughput line.
- a segment can preferably be attached to the supporting structure from an external position. Particularly when it is installed during operation, different metal products and / or materials can be manufactured flexibly in conjunction with a corresponding production planning.
- at least two segments are arranged on a common support structure. Ideally,> 3 segments can be attached to the supporting structure. This shortens the time required to change the process control.
- the support structure preferably has at least one coupling and / or at least one support plate for connecting several segments. In this way, different segments can be transported at the same time via a common drive device.
- a coupling the segments are arranged directly on the supporting structure; in the case of a supporting plate, the segments are placed together on a flat structure which is attached to the supporting structure.
- At least one segment preferably has rollers for conveying the metal product along the passage line.
- rollers for conveying the metal product reduces the likelihood of surface damage. In particular when the conveying temperatures are high.
- a furnace segment ideally has inductive heating.
- the metal product can be heated quickly as a result.
- a furnace segment preferably has at least one furnace door, preferably two furnace doors, for sealing off the furnace chamber from the atmosphere. In this way, for example, a specific furnace atmosphere can be maintained outside the flow line and reduces the flushing time when the furnace segment is reinserted into the line. This also reduces the energy losses caused by the furnace segment cooling down.
- a segment, preferably an exchangeable segment preferably has a measuring device, preferably for detecting the surface quality. As a result, a measuring device can only be used if this appears necessary for the metal product and thus saves maintenance costs.
- a segment preferably has a device for treating the surface, in particular by flaming, descaling, blowing off and / or grinding.
- a device for treating the surface in particular by flaming, descaling, blowing off and / or grinding.
- the surface of a metal product can be flexibly treated differently and brought into a desired state. This improves the metallic extraction, since only the treatment method is used that eliminates the defects with the least amount of material removal.
- At least one segment preferably has a positioning means for aligning the segment in the flow line.
- the positioning means allow the segment to be reliably positioned along the passage line and thereby improve the passage of the metal product through the entire device.
- Segments preferably segments that are adjacent to one another, ideally have complementary coupling components for releasably connecting the segments to one another.
- the coupling in particular in connection with a bracing of the segments with one another, improves the rigidity of the entire device and thus the passage of the metal product through the device.
- a plurality of the segments, more preferably all of the segments, of the device are preferably exchangeable by means of the transport device. This increases the flexibility compared to the concepts from the prior art.
- a roughing stand of a hot rolling train is preferably located at the beginning of the continuous line; preferably there is a finishing stand at the end of the throughput line a hot rolling mill arranged.
- a metal product of particularly high quality can be produced between these two rolling mills by means of a special temperature control, preferably in connection with the detection of surface defects and / or the removal of surface defects.
- a higher-level control or regulation is ideally available for the segments.
- the configurations possible through the flexible use of the segments can be used particularly advantageously if the use of the segments and the segments themselves are carried out by a control or regulation, preferably fully automated and online. In particular when the control or regulation is connected to a higher-level production planning or control.
- the object of the invention is achieved with a method having the features of claim 18.
- a segment is replaced the process control, in particular the temperature control, changed along the direction of flow of the metal product.
- the exchange of a segment for another, neighboring segment takes place in a coherent operation by means of a transport process by a transport device.
- the segments arranged on a common supporting structure are moved, preferably on rails and / or preferably transversely to the line of passage of the adjacent segment.
- the segments are ideally exchanged within 30 minutes, preferably 15 minutes, even more preferably within 5 minutes, these short ones Change intervals reduce the interruption of production in the entire production if a change in the process control is necessary.
- the control or regulation preferably influences the process control, in particular the temperature control, and on the basis of predetermined data, preferably automatically, initiates the exchange of a segment in order to change the process control and / or acts on the individual segment. This reduces the likelihood of errors in the system operation and simplifies the handling and management of the system
- the control or regulation preferably determines suitable materials of the metal products for the segments present in the flow line or for the material of a metal product through the segments to be arranged in the flow line.
- a possible change in a segment by means of an adapted production planning can be dispensed with or a necessary change in a segment can be brought about in a targeted manner. Both can increase the productivity of the plant.
- the metal product is preferably transported along the passage line by means of rollers.
- rollers In particular with slabs or thin slabs as well as the pre-strip after a roughing stand, surface defects are difficult to eliminate. Rollers reduce the likelihood of surface defects here.
- FIG. 1 shows a system diagram for a device according to the invention with two segments S2, S3 following one another in the passage line L.

- Figures 2a, 2b and 2c each show a system scheme for the device.
- Position 1 is a gas-fired furnace segment S2 and position 2 is an encapsulated roller table S4. Both segments are in principle arranged interchangeably on supporting structures 7, but only segment S4 has two available interchangeable segments S1, S3.
- these exchangeable segments are an inductive furnace segment S3 and a roller table S1, which are also arranged on the support structure 7 at position 2.
- the supporting structure 7 belonging to position 1 has no further exchangeable segments, but is designed to accommodate exchangeable segments if necessary.
- All segments of this exemplary embodiment have individual drive devices D which can set a segment in motion individually.
- a motor drive is preferably used for this purpose.
- the supporting structures 7 are designed as rail systems on which the segments can be exchanged while moving or sliding.
- segment S4 all couplings for the associated media supply must be released; any couplings for segments in flow direction D must also be released.
- a segment is exchanged by collision-free, preferably synchronous transport of all three exchange segments S1, S4 and S3 perpendicular to the line of passage in one of the two directions of the double arrow R2.
- the exchangeable segments can be transported synchronously for two or three segments. Alternatively, sequential transport can also take place.
- roller table S1 If the roller table S1 is to be transported into the throughput line L, it must be transported to the left when viewed from the throughfeed direction L. If the inductive furnace segment S3 is to be transported into the flow line L, it must be transported to the right as seen from the flow direction L.

- the drive can be motorized or a cylinder.
- a segment is exchanged by transporting all three exchange segments S1, S3 and S5 on the common platform P perpendicular to the passage line L in one of the two directions of the double arrow R2. If the roller table S1 is to be transported into the flow line L, it must be transported to the left as seen from the flow line L. If the roller table segment with surface inspection S5 is to be transported into the passage line L, it must be transported to the right when viewed from the passage direction L. In both transport cases, the segments are transported at the same time.
- FIG. 2c shows an arrangement of the segments corresponding to FIG. 2b.

- Position 1 is a gas-fired furnace segment S2, positions 2 and 3 each have a roller table segment S1.
- Each position 1 to 3 has its own assigned supporting structure 7 for two segments.
- a supporting structure 8 is arranged parallel to the direction of passage L.
- the supporting structures 7 and 8 intersect.
- Further segments are arranged on the supporting structure 8, namely an inductive furnace segment S3, a further gas-fired furnace segment S2 and a roller table with scarfing device S6. All segments have individual drive devices D.
- the associated installation space on the supporting structure 8 must initially be unoccupied so that the segment S1 can be transported from the passage line L out in the direction of the double arrow R2 onto the parallel supporting structure 8.
- the segment that is to be transported into the passage line L is now positioned in front of the passage line L at position 2.
- all the segments located on the parallel support structure 8 are moved collision-free, preferably synchronously in the direction of the double arrow R3, so that the segment to be exchanged is now in front of the empty position 2.
- the segment to be exchanged can be transported in the direction of the double arrow R2 into the flow line L and is therefore in the operating position.
- Position 1 is a gas-fired furnace segment S2, positions 2 and 3 each have a roller table S1. Each position 1 to 3 has its own assigned supporting structure 7 for two segments.
- a supporting structure 8 is arranged parallel to the direction of passage L.
- the supporting structures 7 and 8 intersect.
- Further segments are arranged on the supporting structure 8, namely a roller table S1 and a further gas-fired furnace segment S2.
- the segments are connected to one another and arranged on the common support plate P. None of the segments has an individual drive.
- a roller table segment with water descaling S7 is positioned in a parking position 9 in spatial proximity to the segments.

- the segment that is to be transported into the through-line L is now positioned in front of position 1.
- the support plate P is moved on the parallel support structure 8 in the direction of the double arrow R3, so that the segment to be exchanged is now in front of the empty position 1. Since the segments are transported together on the support plate P, a drive D is only assigned to the transport plate P and not to each segment. In the following step, the segment to be exchanged can be transported in the direction of the double arrow R2 into the flow line L and is therefore in the operating position.
- the segments are transported in the direction of the double arrow R2 with the aid of a respective central drive D.
- the central drive D can be designed in the form of a cylinder or a motor drive which is coupled to the respective segment. In this way, segments can also be moved individually without their own drive device.
- the number of segments arranged one behind the other in the passage line L can be increased as desired in both exemplary embodiments of FIGS. 3a and 3b.
- the additional transport direction according to the double arrow R3 enables additional flexibility and an increased number of exchangeable segments to be achieved.
- FIGS. 1 to 3 for exchanging segments S can not only be used for adapting a temperature control, they are also suitable to the same extent for carrying out maintenance measures. If a defective segment S or a segment intended for maintenance is removed from the throughput line L and replaced by another segment S, repair and maintenance work can be carried out with reduced downtimes. Any necessary cooling and warming up times can take place outside the throughput line L and do not affect the process management.
- FIG. 4 shows an adaptation of the process control for different metal products and a corresponding schematic temperature profile, in connection with the controller ST.
- the metal product A is a metal product in which the material requires a high forming temperature. The surface requirements are, however, comparatively low. To set a special structure, the metal product B requires intermediate cooling and brief and rapid heating before the piercing in the finishing stand. Furthermore, the surface is descaled in a controlled manner.

- the data of the necessary process control such as the temperature sequences for the metal product A
- the control ST only initiates the exchange of the segments.
- the data record supplied to the control ST does not contain any finished information about the required process control. In this case, the control ST makes the necessary calculations for process control itself and then initiates the necessary compilation of the segments.
