Abstract

PURPOSE:To improve the productivity by performing the hot-rolling leaving an unjoining part on the top part and the bottom part at least of the joining surface at the time of superposing slabs and joining these together after removing an oxide on the superposed surface in advance. CONSTITUTION:The slabs whose oxide on the surface to be joined are removed in advance by grinding with a grinder, shot blasting, etc., are superposed and joined together. At the time of joining, the top part 2 and the bottom part 3 of the joining surface are made to the unjoining part at least. After this, the hot rolling including a reversible pass is performed. By this method, the productivity can be improved.
