在矿山、冶金、建材等行业广泛使用反击式破碎机破碎物料,反击板锤是其主要抗磨配件,耗用量很大。过去用来制造板锤的材料主要是高锰钢,但其加工硬化效果较差,在玻璃行业用于破碎砂岩时,一只板锤的寿命仅几小时,破碎量只有30吨左右。近年来有人采用高铬铸铁制造板锤,抗磨性较好,寿命是高锰钢的4倍以上,但由于其韧性较低,所以抗意外冲击能力差,易断裂。为此,我们采用双金属复合浇注的方法,研制成双金属复合反击板锤。经一年多实际使用,寿命较高锰钢板锤提高3—4倍,抗冲击性能亦较好。 In mining, metallurgy, building materials and other industries extensive use of crusher crusher material, counterattack hammer is its main anti-wear parts, consumption of large. In the past, the materials used to make the slab hammers were mainly high manganese steel, but their work hardening was poor. When used in the glass industry for breaking sandstone, the hammer life of a slab was only a few hours and the crushing capacity was only about 30 tons. In recent years, some people use high-chromium cast iron plate hammer, better wear resistance, life is high manganese steel 4 times, but because of its low toughness, so anti-accidental impact ability is poor, easy to break. To this end, we use bimetallic compound casting method, developed into a bimetallic composite strike hammer. After more than a year of actual use, higher life expectancy manganese plate hammer increased 3-4 times, the impact resistance is also better.
