摘　　要：通过对三种有代表性的直接还原工艺进行分析,认为MIDREX工艺和HYL_III工艺时是当前技术最成熟的直接还原铁工艺.BL法实现了跨行业合作,为技术创新开拓新方向,适合我国煤多气少的国情.直接还原工艺在我国发展缓慢,但市场需求大,有很大的发展空间.MIDREX process and IIYL_III process are considered as the most mature direct reduction processes at present by analyzing three kinds of representative direct reduction processes. BL method achieves the cooperation of c,＇oss industry, which opens up a new direction for technological innovation and is suitable for the co,ditions in China for it has more coal and less gas. The development of direct reduction is slow in China, but the market is huge with a huge space.
