Rolling mill, for extra-thin product range, combines thin slab caster and roll stand train with interposed descaler and heat-treating furnace followed by lengthed strip-to-coil winches

摘要

The layout combines a caster (1) for endless thin slab which is then sheared (2) to finish-rolled coil length or lengths. The layout includes a roller-hearth furnace (3) to heat-treat the lengthed slabs followed by a descaler washer (5) and seven-stand roll train (7). A second descaler (6) is placed between first (F1) and second (F2) stands of the train which terminates in a cooling sector (8) and shear (9) to divide up the semi-endless rolled strip for coil winches (10). Strand guidance is adjustable or again the slab caster is followed by a primary stand to reduce slab thickness. An induction heater should be provided between stands (F1-F7).
