PURPOSE:To perform rolling and finishing work in succession to the rolling smoothly by setting the inlet speed of the front side rolling stand of a repeater higher than the outlet side of a rear side rolling stand and providing a space between the leading and trailing materials of the rolled materials which are cut with a cutter during traveling. CONSTITUTION:A slab is inserted from a rolling stand 3a part to a rolling line 1, and is bisected to a leading material W1 and a trailing material W2 with a crop shear 6 during traveling. The materal W1 is guided by the outside wall 8 of a repeater 4 and advances at the speed equal to the outlet speed V2 of a rolling stand (f) until its leading end is bitten in a rolling stand 3g. Then, the material W1 is pulled and driven at the speed V1 by the stand 3g, and since this speed V1 is set larger than the speed V2, the advancing locus in the intermediate part of the material W1 moves to the position nearer the inside wall 7 of the repeater 4. On the other hand, the material W2 is driven by a rolling stand 3f at its outlet speed V2, is guided by the outside wall 8 of the repeater 4 and advances. |
