Production Practice of Ultra Large Barrel Parts of 30CrMnSiA Steel
In this paper,the production and manufacturing of ultra large barrel parts is introduced,including electric furnace smelting,LF refining,VD degassing treatment,upsetting,drawing-out and forging of intermediate billets,rolling and forming of ultra large barrel parts blanks,heat treatment equipment and processes,and the whole process of production practice.After inspection and analysis,the 30CrMnSiA steel barrel component has high purity of molten steel,fine grain size,excellent mechanical properties,and its ultrasonic test results meet the requirements.The rationality and feasibility of adopting radial and axial rolling production and manufacturing processes for large ring forgings and cylinder forgings have been verified.
