据“铁钢”,72(1986)15号与“铁钢”,77(1992)7号报道,熔融还原法作为21世纪的炼铁技术已引起世界性的关注。很早以前,就在研究不用高炉的炼铁法,熔融还原法就是其中的研究项目之一。不过,除特殊情况外,都未达到实用化程度,因此,炼铁一直没有摆脱高炉法。高炉法虽说经过多次改进已达到高度化程度,但这种高度化在很大程度上都依赖于外围技术即烧结矿与 According to “Iron Steel”, No. 72 (1986) No. 15 and “Iron Steel” No. 77 (1992) No. 7, the melting reduction method has attracted worldwide attention as a 21st century ironmaking technique. A long time ago, studying the ironmaking method without blast furnace, the melting reduction method was one of the research projects. However, except in exceptional circumstances, they have not reached the level of practicality. Therefore, the iron and steel industry has not got rid of the blast furnace law. Although the blast furnace method has reached a high degree of improvement after many improvements, but this degree of reliance on a large extent depends on the peripheral technology that sinter and
