1.高炉二步法用贫锰矿炼锰铁新工艺(三等奖) 由新余钢铁厂、钢铁研究总院和北京钢铁设计研究总院研究成功的“高炉二步法用贫锰矿炼锰铁新工艺”,解决了高炉用贫锰矿直接炼高牌号锰铁的技术问题.高炉二步法生产优质锰铁,工艺稳定、可靠,锰铁含量达到78%,锰元素的回收率比电炉法冶炼提高8.9%.1979年至1983年,已用该工艺生产高牌号锰铁2.7万吨,除供国内使用
1. Blast furnace two-step lean manganese ore ferromanganese new technology (third prize) by the Xinyu Iron and Steel Institute, Institute of Iron and Steel Research Institute of Beijing Iron and Steel Research Institute of successful research “blast furnace two-step lean manganese ore ferromanganese new Technology ”to solve the blast furnace with poor manganese ore direct refining of high grade ferromanganese technical problems. Blast furnace two-step production of high-quality ferromanganese, the process is stable and reliable, ferromanganese content of 78%, manganese recovery rate higher than the electric furnace smelting 8.9% from 1979 to 1983, the process has been used to produce high-grade ferromanganese 27,000 tons, except for domestic use
