[0002] In recent years, the double-sided milling process has been used to replace the old pickling method after hot rolling of strips. As a result, the thickness of the hot-rolled strips has been increased from 6-8mm to 10-15mm, and the thickness of the horizontal continuous casting copper strips has also reached 12-16mm, thereby increasing the thickness of the incoming material of the cold rolling mill. This has put forward new requirements for the copper strip cold rolling mill. In order to increase the blanking capacity and reduce the number of rolling mills, various forms of cold rolling mills have appeared abroad in recent years.
