PURPOSE:To prevent the rippling of a joining face and to better the quality of a composite sheet by annealing the composite sheet at the time when the plate thickness does not exceed a specified value by the rolling reduction rate inversely operated from the product thickness of a composite sheet at the final cold rolling stage. CONSTITUTION:A metal clad sheet of good quality can be obtd. with hardly generating rippling in cold rolling thereafter because the internal stress exerted on the joining face accumulated so far is removed by annealing a composite stock once at the time of the plate thickness when the rolling reduction rate inversely operated from the product thickness does not exceed 70% in order to restrain a cold rolling reduction rate to the degrees causing no rippling. |
