Equipment that complies with one of the previous claims. Where the total length of The oven will be between 250 and 330 m. 7. Equipment corresponding to claim 6 where the first and second areas will be arranged. It is placed separately at a distance of 4 to 25 m when measured in the standard direction of movement. 8. Equipment corresponding to claim 7, where such distance between the first area and the area. The second is equal to 5 to 17 meters. 9. Equipment corresponding to claim 6, 7 or 8, either. Where the second area will have Length between 25 and 100 m 1 0. Equipment corresponding to the claim. Any of the claims 6 through 9, where the area where Two are included. Parts for Reheating and Section for Heating 1 1. Equipment complies with any of the claims 6 to 10, whereby the For elimination, heat transfer from the flat plate to the environment is arranged between areas. First and Second Area 1 2. Equipment corresponding to one of the previous claims. Where the device will receive Preparation with a second oven for flat laying 1 3. Equipment complying with claim 12, where at least one of the first And the second oven is provided with a conveyor for conveying the flattened sheet from the furnace. Bake the second to the first oven 1 4. Equipment corresponding to claim 13, provided that the conveyor path is included. Called parallel ferries 1. 5. Equipment corresponding to any of Claims 12 through 14 where a second oven is provided with a section for additional heating. Second part And for The second heating element placed at the end of the section for additional heating is the second as seen from the standard direction of motion of the flat plate 1 6. What does the device correspond to the previous claim? one In which the oven will be It is provided with the first additional heating section. And the first part for heating, which It has been positioned at the end of the section for additional heating, the first on the inlet side of the oven as seen from the standard direction of motion of the flat plate 1 7. The device complies with the previous claim clause. Any of the above Where at the end of the oven When viewed in the standard direction of motion Will be provided with a section for the heating that Other than that That have been placed at the destination side of the conveyor And is at the source side of Machinery for welding, if there is 1 8. Process for producing steel strips Where the molten steel is obtained in the machine For one or more continuous casting to form flat panels less than 120mm thick by casting heat. And will be transported through the oven And has been rolled in equipment for Rolled to form a steel strip of the required thickness. Where continuous flat sheets Which may have been Thickness reduction already It is obtained welded together by fusing the narrow end surface. By welding And the flat sheets that have been welded together will then be rolled in the process. Endlessly by the device for ironing The position of the weld will move with the flat plate and the flat plate, after which they have been welded together. It will be causing the consistency of The temperature rise at the weld is at least 1. 9. Process corresponding to claim 18, where the sheet is flattened from the machine for welding. The two successive forms will be connected together 2 0. The process complies with claim 18 or 19 where the flattens from the machine to Multi-platen continuous casting will be joined together in 2 1. Process consistent with any one of Claims 18 to 20, where a number of ovens will be used in parallel. And a flat sheet from that oven will receive Connecting together Using a device for welding 2 2.
