摘　　要：为使球铁机油泵齿轮的铸态性能达到QT600-10要求，采用如下技术措施：①通过选用合理的化学成分，采用冲天炉与电炉双联熔炼工艺，进行两次脱硫获得高温低硫原铁液；②采用加盖法球化处理工艺，来提高镁的吸收率；③选用低稀土球化剂，降低球化剂加入量，从而降低生产成本；④采用含Ba、Sb的孕育剂，来得到合适的铁索体和珠光体比例。In production experiment, through selecting rational chemical component for use, adopting the pair smelting craft of the cupola and electric furnace and carrying on the desulphurization two times to obtain low sulphur liquid iron with high temperature, using tundish--cover nodulizing process craft , choosing low rare earth nodulizer and the rational craft of inoculation, the as--cast Gear Oil Pump ductile iron has been developed.
