控制带材平直度和控制带材整个宽度上厚度均匀性,关键在于必须补偿轧制时产生的轧辊挠度。通常,借助于原始的辊身凸度和弯辊系统来补偿轧辊挠度,但是这些控制方法的效果是极为有限的,而且也难于处理带材尺寸和材质的变化。住友金属工业公司发展了一种轧辊凸度可 The key to controlling strip flatness and controlling strip thickness over the entire width is to compensate for the roll deflections that occur during rolling. In general, roll deflections are compensated for with the aid of the original roll crown and roll system, but the effectiveness of these control methods is extremely limited and it is also difficult to handle changes in strip size and material. Sumitomo Metal Industries has developed a roll crown can be
