The Development of the High-Speed Train Axle EA4T Steel with Continuous Casting Technology

摘要：

　　The high-speed train axle EA4T steel was successfully developed through the process optimization of electric arc furnace smelting,(LF+RH)refining,the great round bloom continuous casting,heat treatment in Masteel.The controlling precision of axle steel compositions is high,the chemical compositions segregation of bloom is small,S,P,TO and non-metallic inclusion content in steel are low.Through the optimization of heat treatment process,the mechanical properties of the axle billet is stable,strength,toughness and plastic of the axle billet matches well.
