1450mm热轧生产线上阶梯垫的新型算法

A new calculation method on stepped shim applied in 1450mm hot rolling line

在以往热轧机上阶梯垫的选择过程时,只考虑了上工作辊的磨损,而没有结合上支承辊加入以及上支承辊的磨损问题,出现了无法装辊,或者装辊后由于HGC缸伸的过长,出现设备损坏等现象。介绍了上阶梯垫的新型算法,解决了以上问题。经过国丰钢铁厂试用,取得了成功的经验。

The wear of WR is considered for selection of stepped shim which is used in hot rolling line.But the wear and assembling of BUR is not considered.Some disadvantages appeared,for example,unable changing roll and HGC too long to equipment damaging.A new calculation method is introduced in this paper.The problem mentioned above is solved and the method have achieved success experience in Guofeng Iron and Steel Company.
