摘　　要：针对反击式破碎机专用锤头因磨损而失效的特点,研发了一种蜂窝型双金属复合型锤头。该锤头以高锰钢作锤体,高铬铸铁作耐磨棒,并采用特殊镶铸工艺,将耐磨棒弥散分布于锤头端部。锤头内耐磨棒与基体结合牢固、抗冲击能力强,大幅度提高了锤头使用寿命,从而降低了锤头综合使用成本。Aimed at the failure characteristics of the hammer used in counterattack-type crusher due to wear, a type of honeycomb-type bimetallic hammer was developed. The hammer was made by taking high manganese steel as the hammer body and high chromium cast iron as the wear-rods, and using a special insert-cast process to inserting the wear rods into the end of the hammer. The wear rods and the hammer body have a solid combination and strong impact, improving its life of hammer, reducing the use cost of hammer.
