高铬白口铸铁与磨球(待续)

High Chrome White Cast Iron and Grinding Balls

分析了高铬白口铸铁材质硬度、韧性、基体组织与磨球抗磨性的关系。分析了残余奥氏体,碳化物的数量、形态及分布对磨球抗磨性的影响。通过对磨球工况条件的研究分析及探讨,提出了磨球对材质的性能要求。在生产实践中,用辩证统一的方法,解决磨球材质诸多因素存在的矛盾及存在的相互关系,从而使各因素得到最佳配合,达到相对统一,提高磨球抗磨性的目的。

This article studied the relation between hardness,toughness and the microstructure of high chromium white iron and the abrasion resistant of the grinding balls,analyzed the influence of the residual austenite,the quantity,shape and distribution of carbide on the abrasion resistant,then proposed the performance requiremen of material under the certain operating mode,finally improved the abrasion resistant.
