【摘要】 介绍了一种新型磨球材质—低锰复相球墨铸铁,该铸铁经适当的热处理便可获得所需要的组织,采用特殊的淬火介质可保证Φ40～120mm磨球完全淬透而不产生淬火裂纹,使综合性能指标得到较大提高。更多还原

【Abstract】 This paper introduces a new grinding ball meterial, low manganese duplex structure ductile iron. Expectant structure can be acquired by suitable heat treatment. By means of special quenching medium, Φ40～120mm grinding ball can be completely quenched without quench crack and the synthetical mechanical property is raised greatly.更多还原
