摘　　要：以T10A钢为研究对象,通过省去随炉降温过程,采用延长保温时间的方法,探寻节约时间和成本的球化退火工艺。利用光学显微镜和扫描电子显微镜(SEM)观察样品的表面形态,Imageproplus6.0进行碳化物颗粒统计分析。实验结果表明:Φ13mm的T10A钢在700℃入炉升温至760℃保温10min,迅速转移至690℃保温80min后空冷,可获得碳化物球化程度CS3级组织,心部组织与表层组织的碳化物颗粒均匀性,均高于普通球化退火和等温球化退火,且硬度与等温球化退火一致。此球化退火工艺在保证质量的前提下,碳化物的球化时间极大缩短,可提高生产效率、降低成本、提高能源利用率,拥有较好的工业化应用前景。In this paper,the spheroid zing annealing process for T10A steel were studied. The surface morphology of the sample was observed by optical microscope and scanning electron microscope (SEM) and the Image pro plus 6.0 was used for statistical analysis of carbide particles. The results showed that Φ13 mm T10A steel at 700 ℃ charging temperature to 760 ℃ heat preservation for10 min, move quickly to 690 ℃ heat preservation of air cooling after 80 min, can obtain the degree of carbide spheroid zing CS3 level organization. The homogeneity of carbide particles in the core and surface tissues was higher than that in the ordinary spheroid zing annealing and isothermal spheroid zing annealing. The hardness of the steel was consistent with the steel treated by isothermal spheroid zing annealing. The spheroid zing time of carbides was greatly shortened by this process. It is conducive to improving production efficiency, reducing costs and improving energy efficiency therefore it has a good prospect of industrial application.
