ROLLING METHOD FOR COLD ROLLED STEEL SHEET

摘要

PURPOSE:To prevent the torsion of rolled stock at the time of rolling a cold rolled sheet by roll cross rolling excellent in shape control function. CONSTITUTION:At the time of executing cold rolling by roll cross rolling method, the cold rolled sheet is rolled by parallel rolling method at least the final stand (in the case of a tandem mill) or at least the final pass (in the case of a reversing rolling mill). The torsion of rolled sheet that is generated in roll cross rolling can be prevented by comparatively simpler method. Thus, the high-quality cold rolled steel sheet can be manufactured with high productivity.
