摘　　要：以国内磁选铁精矿为原料制备的氧化球团综合性能良好,可作为竖炉直接还原用氧化球团。国内适合于煤气化的褐煤和低变质烟煤资源储量较大,占煤炭资源总量的50%以上,可以满足煤化工发展的需求。综合煤种需求、生产能力、煤气品质以及能耗指标,选取适宜的煤气化工艺,形成以煤制合成气为还原剂,以竖炉为反应器的煤制气-竖炉直接还原炼铁新工艺,是天然气匮乏而煤资源丰富的中国发展直接还原铁生产、实现低碳高效炼铁的有效途径。The oxidized pellets,which are prepared from domestic magnetic iron concentrate,show good comprehensive performance and can be used in gas-based shaft furnace to produce direct reduction iron.Lignite and low metamorphic bituminous coal reserves in China for the coal gasification accounts for 50% of all coal reserves and can meet the needs of the development of the coal chemical industry.The new gasification-shaft furnace direct reduction iron-making process takes the coal-formed gas as the reductant and the shaft furnace as the reactor,considering the demand of coal,the ability of production,the quality of coal gas and the index of energy consumption,and selecting the suitable coal gasification form.The new process is an effective way to develop direct reduction iron and low carbon ironmaking in china where nature gas resource is poor and noncoking coal resource is rich.
