为提高钢球质量,降低精矿成本,增加经济效益,攀枝花冶金矿山公司从1981年2月开始,组织有关人员进行钢球质量攻关,做了大量试验研究工作,先后完成了钢坯选择,新钢坯制球工艺条件试验、工业性磨矿生产试验和全厂推广应用,使钢球消耗由原1.78公斤/吨矿下降到0.89～1.06公斤/吨矿。按年处理100万吨计,可节省780吨钢球,节约51.60万元。攀枝花选厂是一座大型选厂,采用新钢球后每年节约的费用是相当可观的。本文仅就钢球生产工艺及经济效益作一介绍。
In order to improve the quality of steel balls, reduce the cost of concentrates and increase economic benefits, Panzhihua Metallurgical Mining Company started from February 1981 to organize personnel to conduct quality research on steel balls and did a great deal of experimental research. The company has completed the selection of billet, Ball conditions test process, industrial grinding production test and the promotion of the whole plant, the ball consumption from the original 1.78 kg / ton mine down to 0.89 ~ 1.06 kg / ton ore. Processing 1,000,000 tons per year, saving 780 tons of steel balls, saving 516,000 yuan. Panzhihua plant is a large selection plant, the annual cost savings after using the new ball is considerable. This article only on steel ball production process and economic benefits for an introduction.
