汽车球笼式传动轴用钢Cf53的研制与开发

Research and Development of Cf53 for automobile ball cage drive shaft steel

近年来,汽车制造行业的蓬勃发展,带动了汽车零部件产业的发展,圆钢Cf53是制造汽车球笼式传动轴零件用钢材,要求具有硬度均匀性高、耐磨强度高、疲劳强度高、综合性能好的特点。本文通过制定合理的生产工艺路线、化学成分和圆钢质量控制,通过炼钢工序、连铸工序、轧钢工序的精细化控制,成功开发出汽车球笼式传动轴用圆钢Cf53。

In recent years,the vigorous development of automobile manufacturing industry has driven the development of automobile parts industry.Round steel Cf53 is used for manufacturing automobile ball cage drive shaft parts,which requires high hardness uniformity,high wear-resisting strength,high fatigue strength and good comprehensive performance.In this paper,by making reasonable production process,chemical composition and quality control of round steel,and fine control of steelmaking process,continuous casting process and rolling process,round steel Cf53 for automobile ball cage drive shaft has been successfully developed.
