磨机(包括球磨机、管磨机等)是矿山、建材、化工等工业部门的主要设备之一,衬板是磨机主要易损件之一,其材质较普遍采用高锰钢制造。据知,辽宁省有关厂矿用在磨机衬板制造和备件消耗上,每年需要的锰钢达2～3万吨,1台φ2.7×2.1米规格的球磨机需锰钢衬板23吨,1台φ1.8×6.0米管磨机需锰钢衬板24.5吨。目前,高锰钢衬板不论在质量上和数量上不能满足生产上的需要。因此,开展新型耐磨材料的试验与研究,对我国社会主义的建设和发展,具有重大的现实意义。伟大领袖毛主席亲自发动和领导的无产阶级文化大革命和批林批孔运动,推动了社会生产力的飞跃发展。在“独立自主、自力更生”精
Mill (including ball mill, tube mill, etc.) is one of the major equipment in the mining, building materials, chemical and other industrial sectors. The liner is one of the main wear parts of the mill, and its material is generally made of high manganese steel. It is understood that the relevant factories and mines in Liaoning Province used in the mill liner manufacturing and spare parts consumption, the annual needs of manganese up to 2 to 30,000 tons, a φ2.7 × 2.1 meters specifications of the ball mill manganese steel liner required 23 tons, A Taiwan φ1.8 × 6.0 m tube mill manganese steel liner required 24.5 tons. At present, the high manganese steel liner in terms of quality and quantity can not meet the production needs. Therefore, carrying out experiments and studies on new wear-resistant materials is of great practical significance for the construction and development of our socialism. The Great Proletarian Chairman Mao Zedong personally initiated and led the great proletarian cultural revolution and the campaign to criticize the proletariat and bore holes and pushed forward the rapid development of social productive forces.
