摘　　要：我厂为某公司在DISA线(垂直分型造型线)上开发的差速器壳球铁铸件的铸造生产工艺,采取了无冒口工艺、设冷却片、控制铁水高碳含量、低温快浇、封闭式浇注系统等措施,有效地降低了缩孔(缩松)倾向及其它铸造缺陷。The vertical molding process in Disa-molding line to produce the differential carrier casting with ductile iron is developed. The measures, including non-riser process, quick pouring in low temperature, pressurized pouring system,putting cooling fin, controlling C element of molten iron, and so on are adopted. So the shrinkage (or porosity) defect and other defects in the casting are decreased effectively.
