本厂自1962年开始,采用贫锰矿在高炉中生产富锰渣,再利用富渣在小型敞口电炉中生产碳素锰铁和锰硅合金,收效良好。1980年以后,本厂又用高炉富渣在大型封闭电炉中生产优质锰硅合金,还在用高炉富渣热装生产优质中低碳锰铁和金属锰方面取得了新的成果,并初步形成了以贫锰矿为原料生产优质锰系产品的保证体系。本文重点论述1980年以后的成果。
The factory since 1962, the use of poor manganese ore in the blast furnace to produce manganese-rich slag, and then use the rich slag in a small open-hearth furnace production of carbon ferromanganese and manganese-silicon alloy, with good results. After 1980, the factory also produced high-quality manganese-silicon alloy with blast furnace-rich slag in large-scale closed electric furnace, and also made new achievements in the production of high-quality medium-low-carbon ferromanganese and metallic manganese with blast furnace-rich slag and hot charge, and initially formed To poor manganese ore as raw material to produce high-quality manganese products guarantee system. This article focuses on the post-1980 results.
