非高炉炼铁在不断进步，高炉炼铁流程仍是今后国内外主导发展方向。全面加强中国现有高炉炼铁流程的改造和优化是工作的重点。要注意大型化的合理选择、系统配置和操作参数的改进、过程检测和控制的完善、节能减排路线的制定等。降低铁钢比是减少吨钢CO2排放的最有效手段。
Although nonBF ironmaking processes are developing, BF ironmaking process would still hold its leading position in future in the world. The key for Chinese ironmaking industry is to modify and upgrade operations. Attention should be paid on enlarging BF volume properly, improving configuration and operation indexes, perfecting monitoring and controls, choosing proper energy saving and emission reducing methods, etc. Decreasing the ratio of hot metal to steel is the most effective measure to reduce CO2 emission for steel industry.
