多元低合金耐磨锤头制造工艺

Manufacturing Process for Complex Low-alloyed Wear-resisting Hammers

锤头的耐磨性和工作寿命直接影响着破碎机的工作效率和生产成本,因此锤头要求有良好的力学性能、冲击韧性和耐磨性。在分析了锤头工况和失效机理的基础上,设计了多元低合金耐磨锤头材料的化学成分,提出了铸造工艺和热处理工艺,进行了工业试验,并对试件进行了检测分析,获得了满意的结果。

The operation efficiency and production cost of crusher were directly affected by the performance and service life of hammers. Therefore. hammers were requested to have good mechanical properties, impact toughness and abrasive resistance. Based on the analysis of working condition of the hammers and the failure mechanism, the chemical composition of multi-element low-alloy wear-resistant material for hammers was designed, the program of casting process and heat treatment process were proposed, the industrial test was carried out. and the satisfactory results were obtained.
