Hot strip mill for hot strip of 0,5 mm thickness |
摘要 |
Production of a hot rolled strip with a final thickness below 1 mm out of a cast strip in successive steps is claimed, in which the solidified strip from the casting installation (2, 2') is cut into lengths and is heated in run-through furnaces (4, 4') to its rolling temperature. After descaling the cast strip with a maximum thickness of 90 mm is rolled in a reversing mode in the tandem roll stand group (7). After the first and second pass it is coiled/uncoiled in furnaces (8, 9). After the third pass the strip is coiled for intermediate storage in a coiling unit (10) with two furnaces arranged on top of one another. Simultaneously with coiling of one strip segment, another segment is uncoiled and welded to the end of a previously uncoiled segment in a welding machine (12). The endless strip thus produced passes through another storage unit (13) into a finish rolling section (15). |
