Discussion on Optimizing Deformation Process to Enhance Mandrel Utilization Factor

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.
