摘　　要：讨论了新一代钢厂副产煤气平衡与利用方案,分析了新一代钢厂与发电、建材、石化等行业形成工业生态链的途径。研究表明:年产粗钢900万t的新一代钢厂,通过钢厂副产煤气的充分利用并集成到发电上来,可建设装机容量约90万kW的电站,实现电力自给,充分发挥钢厂能源转换功能;通过冶金渣再资源化利用,建设年产水泥约350万t、水泥微粉约80万t的生产线,与建材行业链接;并有可能外供氢气约6.6亿m3/a,与石化行业形成生态产业链或作为清洁汽车燃料,从而实现生态化转型,适应和促进中国循环经济的发展。Balance and utilization modes for by-product gases of new generation steel plant and approaches to form coo-industrial chains with power generation, cement industry and petrochemical industry are analysed. For a new generation steel plant of 9 Mt per year in capacity a power station of 900 MW could be built to realize electricity selfsupply and to play the function of energy conversion through full utilization of by-product gases and integration to power generation, a cement plant of 3.5 Mt/a Portland cement and 800 kt/a cement fine could be constructed to chain with cement industry through recycling of metallurgical slag, and to provide 660 Mm^3/a hydrogen for petro- chemical industry to form coo-industrial chain or for automobile as clean fuel to realize coo-industrial transformation and to adapt and promote the development of circulative economy in China.
