摘要
介绍了30CrMnSiA钢超大型桶制件的生产制造,从电炉冶炼、LF精炼、VD脱气处理、中间坯的镦拔锻造、超大型桶制件毛坯的轧制成形、热处理装备及工艺等全过程的生产实践。经检验分析,30CrMnSiA钢桶制件的材料纯洁度高,晶粒细小,力学性能优异,超声检测符合验收要求。验证了大型环锻件、筒体锻件采用径-轴向轧制生产制造工艺的合理性和可行性。
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.
