提高球磨机衬板的使用寿命,对降低备件消耗,减少检修台时,提高设备作业效率,有较大的意义。现在普遍应用的高锰钢衬板,由于在球磨机使用过程中,未能充分发挥其冲击硬化耐磨特性,使用寿命较低。寻求易制造、价格低、质量好的高耐磨衬板材料,一直是多年来试验研究的重大课题。遵照毛主席“备战、备荒、为人民”的伟大战略方针和“独立自主、自力更生”的教导,在大打矿山之仗中,我们组织“三结合”试验研究小组,立足我国丰富的合金元素资源,开展了马氏体冷硬球墨铸铁衬板代替高锰钢衬板的试验研究工作。经过三年多的试验室
Improve the service life of ball mill liner, reduce spare parts consumption, reduce the repair station, improve equipment operating efficiency, have great significance. Now commonly used high-manganese steel liner, due to the use of the ball mill process, failed to give full play to its impact hardened wear-resistant properties, lower life expectancy. Seeking easy to manufacture, low price, good quality high wear-resistant lining material, has been a major issue for many years of experimental research. In line with Chairman Mao’s great strategic guideline of “preparing for war, preparing for war and for the people,” and teaching “being independent and self-reliance,” we organized a “triple combination” pilot study group to base ourselves on our rich alloy element resources, Carried out martensitic cold ductile iron liner instead of high manganese steel liner test research work. After more than three years of laboratory
