奥特昆普公司新概念铬铁合金生产工艺简介

摘要

This paper introduces Outokumpu New Concept Ferrochrome Production Process. The feature of process is the combination of preheating kiln (OPKTM) and steel belt sintering (SBSTM), and it integrates advanced technology of mining, beneficiation, steel belt sintering (SBSTM), preheating, and ferrochrome smelting into one plant. It has obvious economical, environmental and social benefits. Lessons can be learnt from the process, but it should be noted that the investment of steel belt sintering is very big and equipment utilization ratio is very low. Considering that smart power grid is being under construction in China and the amount of distributed green energy source will increase in future. DC furnace, as the option that could use fine ores directly, is a priority selection.%介绍了奥特昆普公司新概念铁合金生产工艺。该工艺以预热窑(OPKTM)和钢带烧结(SBSTM)炉结合为特点，把采矿、选矿、钢带烧结(SBSTM)、预热和铬铁合金熔炼等先进技术集中应用于一个工厂内。经济效益、环境效益和社会效益显著。该工艺可以借鉴，但需要注意的是钢带烧结投资大，设备利用率低。考虑到我国正在建设智能电网，未来绿色分布式能源用量增多，选择直流矿热炉直接利用分矿资源也是一个优先选择。
