摘　　要：介绍了ADI 1050-6前轴为大型农机重要受力件,壁厚相差大,铸件力学性能要求高。通过采用冷铁与冒口联合补缩工艺避免了铸件缩松缺陷;同时选择的合适的化学成分,并通过有效的铁液预处理等四级孕育、球化处理的工艺方案,保证铸件满足高性能材质的基本要求;铸件经过盐浴等温淬火处理提升铸件的力学性能,达成客户要求并实现量产。The front shaft of ADI 1050-6 is an important mechanical part of large agricultural machinery,the wall thickness is different,and the mechanical properties of the casting are high.The shrinkage and loosening defects of castings are avoided by using the combined feeding process of cold iron and riser.At the same time,the appropriate chemical composition is selected,and the process plan of four-stage inoculation and spheroidization treatment such as effective iron liquid pretreatment is adopted to ensure that the castings meet the basic requirements of high-performance materials;After salt bath isothermal quenching treatment to improve the mechanical properties of castings,to meet customer requirements and achieve mass production.
