冷轧薄板较多的用于冲压件,故要求有较高的厚度精度及平直度,目前在提高板厚精度方面已有较为完善的厚度自动控制系统(AGC)来解决,至于如何控制板形,还是今日板带生产技术中的突出矛盾。曾采用过各种手段,并出现了各种形式的轧机。本文将介绍一种控制板形的新方法,即 CVC 技术在冷轧机上的应用;并简述宝钢2030冷连轧机采用 CVC 技术控制板形的方案。一、各种板形控制方式的发展冷轧钢板板形控制的方法就是调节辊缝的形状,使其与入口钢板的断面形状保持一致,以减少沿横断面方向的不均匀延伸。60年代人们控制板形多从改变轧辊凸度入手,
More cold-rolled sheet for stamping parts, it requires a higher thickness accuracy and flatness, the current increase in thickness accuracy has been more perfect automatic thickness control system (AGC) to solve, as for how the control panel Shape, or today’s plate production technology prominent contradictions. Various means have been adopted and various forms of rolling mills have emerged. This article will introduce a new method of controlling the plate shape, that CVC technology in the cold rolling mill application; and briefly Baosteel 2030 cold rolling mill CVC technology to control the shape of the program. First, the development of a variety of plate-shaped control The cold-rolled steel plate shape control method is to adjust the shape of the roll gap, so that the cross-sectional shape of the inlet plate consistent in order to reduce the cross-sectional direction of uneven extension. 60s people control the shape of the plate from the roll crown to start changing,
