熔融还原炼铁技术摘要随着社会经济的发展，高炉炼铁资源短缺与环境负荷日益加重的局面已经充分显现，开发新技术逐步取代传统技术将迫在眉睫，这其中以熔融还原炼铁技术为主要开发对象。
国际钢铁界始终没有停止对熔融还原炼铁技术开发的脚步，本文对现有HIsmelt、COREX和FINEX熔融还原工艺及设备进行了分析研究和综合评价，指出了开发新熔融还原技术的原则，介绍了克服高炉炼铁及COREX、HIsmelt熔融还原法存在的缺点的LSM炼铁工艺。
我们应针对目前存在的问题，开发新的熔融还原炼铁技术。

It is very urgent to exploit new technology to replace the traditional. The smelting reduction ironmaking technology is one of the main research fields. International Iron and Steel sector has not stopped for smelting reduction ironmaking technology development pace. The development for the smelting reduction ironmaking technology was never stopped in the world. This thesis just generates under this background.This paper analyzes and makes comprehensive evaluation of the existing HIsmelt, COREX and FINEX reduction process and equipment, points out that the principle of developing new smelting reduction technology, introduces LSM ironmaking process ,which overcomes existing shortcomings of blast furnace ironmaking and COREX, HIsmelt smelting reduction method.We should be aiming at the existing problems, develop new smelting reduction ironmaking technology.KEY WORDS smelting reduction,COREX,FINEX,HIsmelt,LSM1. 前言高炉炼铁方法从使用焦炭算起已有三百多年的历史，第二次世界大战后的50年来，钢铁冶金技术获得了重大发展。
