优化变形工艺提高芯棒利用效率的探讨

Discussion on Optimizing Deformation Process to Enhance Mandrel Utilization Factor

芯棒是限动芯棒连轧钢管机组中最重要的热变形工具,其使用效果决定着钢管生产成本的高低。针对芯棒用H13型钢的材料特性,通过对机组变形工艺的分析,提出了使用附加孔型对芯棒使用工艺进行优化的办法,以解决报废芯棒再利用的问题。

Since the mandrel is the most critical thermal deformation operation tool for the retained mandrel pipe mill （MPM） process, its operation efficiency is decisive to steel tube operational cost. In order to reuse the scrapped mandrel, an approach to optimizing the mandrel operation is proposed, involving an additional groove introduced on the basis of the characteristics of the H13 steel and the analysis of the deformation process of the mill.
