摘要
介绍了破碎机锤头常用材质的种类、成分、组织和性能特点;综述了破碎机锤头耐磨材料的几种生产工艺及特点。破碎机锤头的耐磨材料要根据破碎物料的种类和设备情况来选择。锤头工作应力较大时,可选择高锰钢或超高锰钢锤头材料,锤头的生产可采用整体铸造的方法;锤头工作应力较小时,可选择合金钢整体铸造或碳钢与高铬铸铁复合铸造方法。复合铸造法生产破碎机锤头,是提高破碎机锤头使用寿命的较好方法。
The kind of common materials for crusher hammers and their microstructure, properties and char- acteristics were introduced, and several processes of manufacturing wear-resistant materials and their charac- teristics were summarized. Wear-resistant materials for the crusher hammers should be selected according to the kind of crushing material and equipment status. While the hammer had higher operating stress, the high manganese steel or ultra-high manganese steel could be selected for hammer material and the hammer could be manufactured by integral casting. While the hammer had lower operating stress, integral casting of alloy steel or compound casting of carbon steel and high chromium cast iron could be selected. The application of compound casting to manufacture of the crusher hammer was a good way to improve the lifespan of the crusher hammer.
