熱軋不銹鋼管生產(chǎn)工藝優(yōu)化的探討

Discussion on Manufacturing Process Optimization of Hot-rolled Stainless Steel Tube

摘要: 簡述熱軋鋼管機(jī)組建設(shè)情況；重點(diǎn)探討熱軋不銹鋼管生產(chǎn)過程中的難點(diǎn)，并提出相應(yīng)工藝改進(jìn)建議。分析認(rèn)為：熱軋鋼管機(jī)組生產(chǎn)不銹鋼管時(shí)的難點(diǎn)在于軋管機(jī)負(fù)載不足，沒有軋制不銹鋼的工藝方案和配套的工藝、工序；建議優(yōu)選管坯加熱方式和加熱制度，優(yōu)化穿孔過程中的金屬變形條件，解決軋管的孔型設(shè)計(jì)問題，提高工模具強(qiáng)度及潤滑效果。

Abstract: Briefed in the paper is the construction of a steel tube hot rolling plant, focusing on difficulties in the producing of hot-rolled stainless steel tube, and corresponding advices are put forward.The analysis indicates that the difficulties of the hot rolling plant in producing stainless steel tube include insufficient rolling load capacity, lack of process scheme for rolling stainless steel tube and absent of adequate process and procedure.It is recommended to carefully select the heating method and schedule for billet, optimize the metal deformation condition during piercing, solve the design problem of rolling pass and elevate tool strength and lubricating effect.
