Abstract

PURPOSE:To reduce elongation difference defect and clad ratio defect parts in the top and rear end parts of a clad stock by performing usual rolling after performing preformative rolling in a specific lengthwise range from the stock top and rolling by a larger draft than that of the preformative rolling. CONSTITUTION:As for hot rolling of a clad stock, the lengthwise range of 0.2-0.8 times the total length of the stock from the stock top end is preformatively rolled. Defining a combination of the preformative rolling with a rolling by a larger draft than that of the preformative rolling from the stock rear end is one pass, then at least two passes rollings are performed. Respective peripheral speeds of upper and lower rolling rolls are made to be different; a material having less extensibility is put at a high speed roll side and rolling is performed in the above-mentioned way. Hence, the yield of the stock is improved.
