Large crusher abrasion-resistant hammer and preparation method thereof

The invention provides a large crusher abrasion-resistant hammer and a preparation method thereof. Elements in raw materials include, by weight, 1.9-2.7% of C, 7-9% of Cr, 0.7-1.1% of Mn, 0.4-0.7% of Mu, 0.3-0.5% of Cu, 0.9-1.3% of Ni, 0.2-0.4% of Si, 0.1-0.3% of Ti, 0.2-0.4% of Be, 0.4-0.7% of rare earth and the balance Fe and impurity components not capable of being removed. The abrasion resistance of the large crusher abrasion-resistant hammer can be further improved through alloy smelting, modification treatment, casting, quenching and tempering, the improvement of the ductility of the hammer is increased, and production and processing treatment and industrialized production and processing are convenient. 本发明提供种大型破碎机耐磨锤头及其制备方法，原料中各元素的重量组分为：C 1.9?2.7％、Cr 7?9％、Mn 0.7?1.1％、Mu 0.4?0.7％、Cu 0.3?0.5％、Ni 0.9?1.3％、Si 0.2?0.4％、Ti 0.1?0.3％、Be0.2?0.4％、稀土0.4?0.7％以及余量的Fe和不可去除的杂质成分。本发明再通过合金熔炼、变质处理、铸造、淬火、回火，使得大型破碎机耐磨锤头耐磨性能够进步得到提升，且增加了其延展性的提升，便于生产加工处理以及工业化的生产加工。
