摘　　要：本文着重研究了宝钢转炉生产的12Cr1MoV钢的高温持久性能。不同冶炼方法和氮含量及不同热处理王艺的持久强度对比试验。试验表明成品管正火后出现的混晶组织并不影响持久性能,提出最佳的热理处工艺制度和按金相组织中贝氏体判断成品管热强性的依据。The high temperature strength of 12Cr1MoV steel produced in converter with different melting processes, nitrogen contents and heat-treatment procedures were studied. The results show that the mixed grain structure formed in normalizing tube does not affect its rupture strength. The optimal heat-treatment procedure and the criterion for high temperature on the basis of tainite has been put forward.
