摘　　要：相对于直接还原和熔融还原工艺,高炉工艺生产规模大,且与转炉结合的高炉-转炉流程净能耗最低,成本最具竞争力,仍是最适应可预见未来的炼铁生产工艺。但未来高炉炼铁生产规模将受制于炼钢的废钢使用量,由此将导致我国未来高炉炼铁生产可能出现下降趋势。认为高炉炼铁工艺不断的流程改进和工序完善,加之持续的革新探索,包括高炉吃废钢、流程优化、操作控制改进、原燃料优化等,将使高炉炼铁工艺长久保持其强大的生命力和竞争力。Compared with the direct reduction process and smelting reduction process, BF ironmaking process still will be the most suitable ironmaking production process in the foreseeable future considering its advantages of large production scale, lowest net energy consumption in case of BF ＋ BOF application, and the most cost-effective production. However, BF ironmaking production scale in the future will be restrained by the scrap percentage in steelmaking, a factor that would result in decline of BF ironmaking production domestically. It is believed that BF ironmaking process can maintain its strong vitality and competition for a long time by means of constant technological improvement, optimization and innovation, including using scrap in BF smelting, upgrading operation and control, and improving quality of raw material and fuel.
