江苏江都水泥机械配件厂在江苏省建材局的帮助下,研制成功新型耐磨材料——中锰铜钼合金球铁。该厂用这种材料已制成各种规格的球磨机衬板、螺栓、钢球等配件,年产能力在一千四百吨以上。该材料选用优质铸铁,在熔炼中控制锰、铜、钼和硅等化学成分,浇铸后再经热处理,使其具有一定韧性和极好的耐磨、抗冲击性能。这种新型耐磨材料的使用寿命比高
Jiangsu Jiangdu Cement Machinery Parts Factory in Jiangsu Province Building Materials Bureau with the help of the successful development of a new type of wear-resistant materials - manganese manganese steel ductile iron. The plant with this material has been made into a variety of ball mill liner, bolts, steel balls and other accessories, with an annual output capacity of more than 1,400 tons. The material is made of high-quality cast iron, which controls the chemical composition of manganese, copper, molybdenum and silicon in the melting process. After casting, it is heat-treated to make it have certain toughness and excellent wear resistance and impact resistance. The new wear-resistant materials have a longer service life
