随着我国钢铁产业突飞猛进的发展,资源环境问题以及钢铁产业内部低端产品多,高端产品少等问题也突显出来。发展流程短、污染小、消耗少的直接还原铁技术再次提上议程。本文在总结国内外直接还原铁生产经验与技术的基础上,对我国利用丰富的煤炭资源发展煤制气竖炉直接还原铁技术的可行性、存在的问题及相应的解决办法进行了分析和探讨,为我国直接还原铁技术的发展提供参考。
With the rapid development of China’s steel industry, the issues of resources and environment, low-end products in the steel industry and less high-end products are also highlighted. The development of short process, pollution, small consumption of DRI technology once again put on the agenda. On the basis of summarizing the experience and technology of direct reduction iron production at home and abroad, this paper analyzes and discusses the feasibility, existing problems and corresponding solutions of using direct coal reduction technology of rich coal resources in China , Provide a reference for the development of direct reduction iron technology in our country.
