摘　　要：COREX熔融还原炼铁工艺采用非炼焦煤直接炼铁,缩短了工艺流程,减轻了炼铁工业对环境的污染,生产过程产生的大量优质煤气可以用于生产热压块。1套COREX C2000装置输出的煤气量和1座年产0.8 Mt的直接还原设备所需要的还原煤气量大致相当。对利用COREX炼铁煤气生产热压块的工艺能量利用进行了分析,指出了竖炉还原过程中的适宜条件和影响因素。The COREX process for hot metal has been known as an advanced technology due to the use of non-coke coal which can shorten the production route, greatly lighten pollution of iron making process, and offgas can be used for production of HBI. The offgas output of COREX 2000 can meet the need of producing 0.8 Mt/a HBI. The energy consumption of shaft production of HBI using COREX offgas,is analysed with presentation of suitable reduction conditions and influencing factors.
