介绍了一种能够达到传统耐磨铸钢———高锰钢的使用性能， 并能缩短生产周期、降低生产成本的中锰耐磨铸钢的成分选择原则和铸造余温淬火工艺。该工艺可应用于一些简单耐磨件的生产。
The principle of composition selection of medium manganese wear resistant cast steel which can achieve the service performance of traditional wear resistant cast steel --- high manganese steel and shorten the production cycle and reduce the production cost are introduced. The process can be applied to the production of some simple wear parts.
