摘　　要：工业纯钛棒材在航空、航天、舰船、核能、军工等高科技领域,均具有广泛的用途。文章借助一条专用于轧制钛及钛合金棒线材的新型热连轧生产线,通过工艺探索,优化?椎73mm大规格纯钛棒材的热连轧生产工艺,并选取适宜的棒材成品热处理制度,获得满足技术条件GB/T13810-2007、ISO5832/2中均匀且5级以上晶粒度评级要求的成品棒材。Industrial pure titanium rods have a wide range of applications in high-tech fields such as aviation, aerospace, naval ships, nuclear energy, and military industry. In this paper, a new type of hot continuous rolling production line for rolling titanium and titanium alloy rods is used to optimize the hot continuous rolling process of φ73mm high-specification pure titanium rods, and a suitable heat treatment system for finished rods is selected., so as to obtain finished rods that meet the technical conditions GB/T13810-2007, ISO 5832/2 uniform and grade 5 or above grain rating requirements.
