在不锈钢线材轧制过程中,不锈钢303Cu等钢种易发生头部开裂的现象,对此,大部分厂家的通常作法是通过对加热方法的调整来控制MnS在钢材中的形态,从而解决轧制过程中头部开裂的问题,或者增加飞剪的切头长度,但改变加热温度(提高轧制温度)可能会引起表面划伤等问题,
In the stainless steel wire rod rolling process, 303Cu stainless steel head prone to cracking phenomenon, which most manufacturers of the usual practice is to adjust the heating method to control the shape of MnS in the steel to solve the rolling The process of cracking the head or increase the shear length of the flying shear, but change the heating temperature (increase the rolling temperature) may cause surface scratches and other issues,
