超细破碎机板锤材质的研究

The study of materials of super-fine crusher hammer

就ＣＪ型超细破碎机板锤的材质进行了研究，结果表明：选用的高铬锰钨合金性能（ＨＲＣ，）与１５Ｃｒ３Ｍ。合金相当，用其生产的超细破碎机板锤是原合金钢板锤使用寿命的２．７倍，取得了较好效果。

The paper study the material of hammer of CJ.super-fine crusher,with the result that HRC allog has the same performance with 15Cr3M allog.And,usable life of super-fine crusher hammer is extended.
