介绍了铸钢性能与其组织和热处理的关系，提出了与锻钢不同的热处理工艺，辅之采用双相钢原理和寻求热处理方法削弱非金属夹杂物的有害作用，可以取得满意的效果。并以行星减速器ZG40Cr转架轴为例进行了分析。
The relationship between the performance of cast steel and its microstructure and heat treatment is introduced. Different heat treatment technologies are proposed, and the harmful effects of non - metallic inclusions are weakened by the dual - phase steel principle and heat treatment method. Satisfactory results can be obtained. And the planetary reducer ZG40Cr turret axis as an example for analysis.
