由金堆城钼业公司、西安交大,铜川钢厂共同研制、生产、试验的高铬铸铁衬板,于1982年12月26日至1984年5月25日在金堆城钼业公司科研所试验厂一号 MQY2400×1200园锥溢流型球磨机中,做湿式工业性试验,历时一年另五个月,实际运行9555小时,处理矿量91149.3吨,证明该种衬板能经得起这种机型的实际考验。在此期间,对同机型的2号机所使用的高锰钢衬板也作了详细的测试工作,两者得出了可信的对比数值。现分述如下:
By the Jinduicheng Molybdenum Company, Xi’an Jiaotong University, Tongchuan Steel jointly developed, produced and tested high-chromium cast iron liner, in December 26, 1982 to May 25, 1984 in Jinduicheng Molybdenum Company Research Institute Test plant on the 1st MQY2400 × 1200 cone overflow type ball mill, do wet industrial test, which lasted another year for five months, the actual operation of 9555 hours, processing mine capacity of 49,949.3 tons, proved that the lining can withstand this The actual test of the models. In the meantime, on the same type of machine No. 2 used in high-manganese steel liner also made a detailed test work, the two reached a credible comparison value. Now as follows:
