目前,市场上大量需求平直度高的极薄和高强度冷轧薄板。为此,日本钢管公司和石川岛播磨重工业公司共同研制了一种新型五辊冷轧机。这种平直度控制灵活的FFC轧机,工作辊直径小,可以在高速下实现大压下量。带双轴承座的弯辊装置的水平弯辊系统,可以在很宽的范围内纠正板形缺陷。 Currently, there is a great demand for very thin and high-strength cold-rolled sheets that are flat on the market. To this end, Nippon Steel Pipe Company and Ishikawajima Broadcasting Heavy Industry Co., Ltd. jointly developed a new five-roll cold rolling mill. This flatness-controlled, flexible FFC mill, with a small work roll diameter, allows large reductions at high speeds. Horizontal bending system with double bearing bending device can correct shape defects in a wide range.
