A METHOD AND A PLANT FOR ROLLING HOT-ROLLED WIDE STRIP FROM CONTINUOUSLY CAST THIN SLABS OR SLABS OF MEDIUM THICKNESS OF ABOUT 40 TO 100MM, WHEREIN THE CAST SLAB STRAND IS DIVIDED INTO SECTIONS (7), IS SUBJECTED TO A TEMPERATURE TREATMENT IN A CONTINUOUS FURNACE (2,3), AND IS CONVEYED FOR ROLLING INTO A ROLLING TRAIN (6). THE TEMPERATURE TREATMENT OF A SLAB SECTION (7) ON THE CONTINUOUS FURNACE (2,3) IS INTERRUPTED BY A SURFACE TREATMENT AND THE SURFACE TREATMENT OF THE SLAB SECTION (7) IS CARRIED OUT IN THE PRODUCTION LINE BETWEEN THE CASTING PLANT(L)AND THE ROLLING TRAIN (6). THE PLANT FOR CARRYING OUT THE METHOD INCLUDES A CONTINUOUS CASTING PLANT (1) FOR THIN SLABS, A TRANSVERSE CUTTING DEVICE(5), A CONTINUOUS FURNACE(2, 3)AND A ROLLING TRAIN(6), WHEREIN THE CONTINUOUS FURNACE, FOR EXAMPLE, A ROLLER-HEARTH FURNACE, IS DIVIDED INTO TWO SEGMENTS BETWEEN WHICH IS ARRANGED IN AN IN-LINE POSITION A SURFACE TREATMENT UNIT FOR TREATING DEFICIENT SLAB SECTIONS (7). |
