【摘要】 研究了铜对冶金耐磨钢衬板抗腐蚀磨损性能的影响，结果表明：在弱酸性（ｐＨ：５．５～６．５）条件下，试验钢的抗腐蚀磨损系数随着Ｃｕ含量的增加而提高，当Ｃｕ含量达１．５％时，试验钢的抗腐蚀磨损系数达到最大值，为高锰钢的２．８９倍。用该试验钢生产的球磨机衬板在钼矿弱酸性湿磨条件下，其使用寿命是高锰钢衬板的３倍左右。更多还原

【Abstract】 The paper studies on the influence of copper on the abrasion resistance of mill linings made from wear-resisting casting steel for metal mines . The results indicate that the abrasion-resisting coefficient of the tested steel increases with the increase of the copper content in the condition of weak acidity . When the copper content is up to 1.5%, the abrasion-resisting coefficient is up to its maximum, which is 2.89 times as high as that of high manganese steel . The service life of the mill lining made from the tested steel is about 3 times as long as that of the linings made from high manganese steel in the condition of wet grinding molybdenum ore with weak acidity.更多还原
