With the vigorous development of the global seamless steel tube industry,high-performance limited-movement mandrels,as key process equipment,have attracted increasing attention in terms of their production process optimization and innovation.Through in-depth analysis of the current research status and process characteristics and difficulties of their production and processing at home and abroad,this article fo-cuses on the optimization of homogenization,grain refinement,heat treatment processes,etc.in the processing of mandrels,and develops a high-performance limited-movement mandrel production process with independent intellectual property rights.This improves the mechanical properties and impact toughness of the mandrel,en-sures the stability and reliability of product quality,and lays a solid foundation for the independent produc-tion of high-performance limited-movement mandrels in China.
