Abstract

A modular rolling train, particularly a hot rolling train, preferably in conjunction with an upstream casting facility, and a method for operating a modular rolling train are described. The rolling train is standardized and modularized by dividing the rolling train into discrete units n and by modularization of the discrete units. The rolling train can be flexibly adapted to new requirements by exchanging a module.

First claim

The invention claimed is:

1. A system for forming a metallic product along a throughput section, comprising:
a casting facility;
a modular rolling train that is subdivided into discrete units along the throughput section, including
a heat treatment unit,
a roughing rolling unit,
a finishing rolling unit, and
a transport unit for moving the metallic product,
wherein at least one of the discrete units is a subdivided discrete unit comprising at least two modules; and

a transport device assigned to the subdivided discrete unit for exchanging the at least two modules,
wherein a first of the at least two modules of the subdivided discrete unit is configured to be exchanged with a second of the at least two modules by the transport device.

2. The system according to claim 1 ,
wherein the subdivided discrete unit is the roughing rolling unit, the finishing rolling unit, the transport unit, or the heat treatment unit, and
wherein the one of the at least two modules is a set of rolls of a roughing stand, a set of rolls of a finishing stand, a roll table, an enclosed roll table, a furnace module, a cooling section, a separating unit, a surface treatment unit, or a measuring equipment.

3. The system according to claim 1 ,
wherein a further of the discrete units is a further subdivided discrete unit with a further transport device being assigned to the further subdivided discrete unit, and
wherein the first of the at least two modules can be exchanged with the second of the at least two modules by a transport operation between the transport device and the further transport device.

4. The system according to claim 3 ,
wherein a length of the modular rolling train is divided into a length grid and a length of the length grid is 0.25 m to 1 m, and
wherein dimensions of the discrete units and/or the at least two modules of the modular rolling train are integer multiples of the length of the length grid.

5. The system according to claim 1 ,
wherein the subdivided discrete unit is a heat treatment unit, and
wherein the one of the at least two modules of the heat treatment unit is a furnace module, a roll table module, an enclosed roll table module, a cooling section module, a surface treatment module, or a measuring section module.

6. The system according to claim 5 ,
wherein the one of the at least two modules is a roller hearth furnace module.

7. The system according to claim 5 ,
wherein the one of the at least two modules is an induction heating module.

8. The system according to claim 1 ,
wherein the subdivided discrete unit is the roughing rolling unit, and
wherein the one of the at least two modules of the roughing rolling unit is a roughing stand with two driven work rolls and/or two support rolls.

9. The system according to claim 1 ,
wherein the subdivided discrete unit is the finishing rolling unit, and
wherein the one of the at least two modules of the finishing rolling unit is a finishing roll stand with two driven work rolls and/or two support rolls.

10. The system according to claim 1 ,
wherein the modular rolling train is a hot rolling train, configured for forming one of different cast products comprising different materials and/or having different dimensions that can be produced by the casting facility, and
wherein the modular hot rolling train is configured to receive the different cast products directly after a casting and solidification process.

11. The system according to claim 10 ,
wherein the casting facility is a continuous casting line, and
wherein an ingot mold of the continuous casting line can be exchanged to change dimensions of the metallic product.

12. The system according to claim 1 ,
wherein the casting facility is a continuous casting line with an exchangeable ingot mold,
wherein the modular rolling train further includes
a second heat treatment unit between the roughing rolling unit and the finishing rolling unit, and
a third heat treatment unit after the finishing rolling unit, and

wherein the second heat treatment unit is the subdivided discrete unit.

13. The system according to claim 12 ,
wherein the modular rolling train can be adjusted to different materials and dimensions of the metallic product by exchanging the at least two modules of the second heat treatment unit,
wherein the second heat treatment unit includes a fixed section and four exchangeable modules,
wherein two of the four exchangeable modules are arranged in the throughput section, and
wherein two of the four exchangeable modules are roller hearth furnace modules and two of the four exchangeable modules are open roll tables.

14. The system according to claim 1 ,
further comprising a higher-level control or regulation system for the modular rolling train and associated control or regulation system for the discrete units and/or the at least two modules,
wherein the higher-level control or regulation system can initiate and execute an automatic exchanging of the at least two modules.

15. The system according to claim 1 ,
wherein the transport device is an overhead crane.

16. The system according to claim 1 ,
wherein the transport unit includes two roll table modules, and the two roll table modules are moved along rails using the transport device.

17. A method for operating a modular rolling train for forming a metallic product, the modular rolling train being subdivided into discrete units along a throughput section, including
a heat treatment unit,
a roughing rolling unit,
a finishing rolling unit, and
a transport unit for moving the metallic product,
wherein at least one of the discrete units is a subdivided discrete unit comprising at least two modules, and
wherein the modular rolling train further includes a transport device assigned to the subdivided discrete unit for exchanging the at least two modules,
the method comprising:
effecting a desired change in format and/or material of the metallic product by adjusting a process control in the modular rolling train based on production parameters, including
checking whether the production parameters can be achieved by a roll gap adjustment and/or adjustment of cooling parameters with modules that are present in the throughput section; and
automatically exchanging unsuitable ones of the modules that are present in the throughput section with modules suitable for compliance with the production parameters.

18. The method according to claim 17 ,
