直接还原铁（DRI）及其在电弧炉中的应用

分析了直接还失得以迅速发展的原因，对主要的直接还原工艺进行了简介，提出了我国发展直接还原铁的方向。通过剖析国外在电弧炉炼钢过程中使用ＤＲＩ的实例，总结了电弧炉炼钢使用ＤＲＩ过程应该注意的主要问题。

DIRECTLY REDUCED IRON (DRI) AND ITS APPLICATION IN ELECTRIC-ARC FURNACE

The reasons of great development on direct reduction of iron have been analyzed in this paper.The main direct reduction process has been also introduced,and meanwhile the orientation of developing directly reduced iron in our country has been indicated herein.By analyzed the example of using DRI in the process of steelmaking in electric-arc furnace in foreign countries,the authors summarized the main notes which we should observe while using DRI in the process of steelmaking in arc furnace.
