摘　　要：钢铁企业面临严峻的二氧化碳减排形势,建立全国性的碳排放交易市场势在必行,钢铁企业提前布局二氧化碳减排战略对企业生存具有重要意义。为了促进国内钢铁企业对减排二氧化碳技术的重视,从国内外二氧化碳减排技术现状出发,介绍了欧洲、日本等国外碳减排技术的研究现状及进展。同时从设备、原燃料、高炉操作等角度分析了国内高炉减排二氧化碳的技术现状,并对二氧化碳减排技术的发展趋势进行了系统介绍。研究认为探索焦炉煤气和生物质喷吹技术、生物质直接还原技术和废塑料喷吹技术,促进高炉渣余热回收、推广烧结矿竖式冷却余热回收技术和高富氧高炉结合碳捕集封存技术等对于二氧化碳减排具有潜在的研究和应用价值。It is necessary to build the national carbon emission trading market at the background of severe emission reduction condition,and it is important to take arrangements beforehand for ironmaking and steelmaking enterprise.To bring about awareness of the technology of the carbon emission,based on the technical status at home and abroad,ultra low carbon steelmaking and COURSE 50 are introduced as well as other technologies for CO_2 emission reduction abroad.At the same time,technologies at home related to raw materials and operation condition are also described.Development of CO_2 emission reduction is analyzed.Research suggests that the injection of coke oven gas and biomass,direct reduction by biomass,injection of waste plastic,waste heat recycling of blast furnace slag,vertical tank cooling for waste heat recycling for sintering and carbon capture and storage combined with blast furnace with high oxygen enrichment are worth investigating in the future.
