冷轧08A1带钢的不同取样部位性能指标相差多大?即沿带钢轧向或垂直轧向性能指标的均匀性如何?这是生产厂和用户关心的问题。我们作了二方面的工作:一是考查了沿轧向卷头、卷中、卷尾性能指标的差异,二是考查了垂直轧向,即沿板宽方向性能的变化。第一方面的工作,我们在冷轧厂随机抽取了25卷1毫米厚的08A1板,平整后在精整 What is the difference between the performance indexes of different sampling sites in cold-rolled 08A1 strip, that is, the uniformity of the performance indexes along the strip rolling or vertical rolling? This is a concern for the manufacturers and users. We made two tasks: First, examined the rolling head, roll, tail end of the performance index differences, the second is to examine the vertical rolling, that is along the width direction of the board performance changes. The first part of the work, we randomly selected in the cold rolling plant 25 1 mm thick 08A1 plate, after the formation of the finishing
