鞍山市红砖厂在锤式粉碎机上利用鞍山市机电研究所试制的铬锰钨铸铁粉碎机锤头,经过一年多使用证明效果显著,解决了粉碎机锤头的耐磨难题。粉碎机上的锤头是粉碎加工过程中最容易磨损的部件。目前还没有固定的材质,多数采用普通白口铸铁和高锰钢(Mn13)等材质。其耐磨性能远远满足不了生产上的需要,已成为生产上的一大难题。铬锰钨铸铁是以锰钨代替较贵的耐磨材质钼,造价低于钼合金,而耐磨性能比钼合金毫不逊色。铬锰钨铸铁化学成分含量(％);C2.4～
Anshan City Red Brick Factory in the use of hammer mill Anshan Institute of Electrical and experimental chromium-manganese-tungsten cast iron hammer mill, after more than a year to prove the use of significant effect to solve the mill hammer mill wear problems. The hammer on the shredder is the most worn part of the shredding process. There is no fixed material, the majority of ordinary white cast iron and high manganese steel (Mn13) and other materials. Its wear resistance far can not meet the production needs, has become a major production problems. Chromium manganese tungsten cast iron is replaced by manganese tungsten expensive wear-resistant material molybdenum, the cost is lower than the molybdenum alloy, and wear resistance than the molybdenum alloy no less. Chromium, manganese and tungsten cast iron chemical composition (%); C2.4 ~
