Abstract：Based on the characteristics of EPC process,combined with the special technical requirements of heavy duty cast-steel engineering axle shell,the heavy duty engineering axle shell was produced by EPC process.The results show that a series of effective measures,such as improved casting process,STMMA bead molding+empty casting,anti-crack ring,bottom leakage ladle+blowing argon casting,frame support+fine operation,the heavy-load engineering axle shell have been successfully produced,and the defects such as carbonization,cracking,inclusion leakage and deformation are solved.At the same time,the high frequency vibration during the casting process refined the casting grains.
