摘要
介绍了KPW50VMR轧管机芯棒用LD钢特性和LD钢芯捧的热处理工艺。通过与德国的A8、MAR350钢芯棒使用寿命对比,LD钢芯棒使用寿命长,制造成本低。
The properties of LD steel for the mandrel of KPW50VMR tube-rolling mill and the heat-treatment process for the mandrel are described, LD steel mandrel has longer service life than A8 and MAR350 steel mandrels made by Germany and its manufacturing cost is low,
