本文在考虑金属三维变形的基础上,提出了求解轧制压力、两向摩擦力和前后张力等横向分布的条元分析法,为模拟带材轧制过程提供了一个简单、有效的新方法。采用现代测试手段——计算机采样,在300mm四辊可逆式冷轧机上进行了冷轧铝带力参数综合测试:沿轧辊轴向布置九个万能测量装置,测定了单位轧制压力、两向单位摩擦力在变形区内的分布,同时还通过多辊式分段张力检测板形仪,测量了前后张力的横向分布,获得了一些新的规律性认识。在宽、厚比达到620,轧后边浪和中浪、对称
In this paper, based on the three-dimensional deformation of metal, the strip-element analysis method for solving the transverse distribution of rolling pressure, two-way friction and anteroposterior tension is proposed, which provides a simple and effective new method for simulating the strip rolling process. A modern test method - computer sampling was used to carry out the comprehensive testing of cold rolling aluminum belt force parameters on a 300mm four-roll reversing cold rolling mill. Nine universal measuring devices were arranged along the roll axis, and the unit rolling pressure, Friction distribution in the deformation zone, but also through the multi-roll segment tension detection plate-shaped instrument, measuring the horizontal distribution of tension before and after, to obtain some new understanding of regularity. In the width, thickness ratio of 620, after rolling the waves and waves, symmetrical
