杂质泵、球磨机、抛丸机、搅拌机等是冶金、矿山、建材、水电、机械等工业普遍采用的通用设备。由于在冲击、摩擦、腐蚀等恶劣的工作条件下使用,往往需频繁的更换易损件,这不仅要消耗大量钢铁材料,而且直接影响了设备的有效利用率。为提高上述通用设备的寿命,国内外对该类抗磨材质(主要是抗磨白口铸铁)进行过大量的研究工作。国外抗磨铸铁主要是研究高铬、高镍的白口铸铁。而对钨白口铸铁则认为得不到满意的耐磨组织,难以具有高的耐磨性。
Impurities pumps, ball mill, shot blasting machine, mixer and other metallurgical, mining, building materials, utilities, machinery and other industries commonly used common equipment. Due to the impact, friction, corrosion and other harsh working conditions, often need frequent replacement of wearing parts, which not only consume large amounts of steel materials, but also directly affect the effective utilization of equipment. In order to improve the life of the above universal equipment, a great deal of research work has been done on such anti-wear materials (mainly anti-wear white cast iron) at home and abroad. Foreign wear-resistant cast iron is mainly the study of high-chromium, high-nickel white cast iron. The tungsten white cast iron is not satisfied with the wear-resistant organization, it is difficult to have high wear resistance.
