摘　　要：温室气体排放引起的气候变暖已经成为全球性的重要命题。介绍了国内钢铁工业温室气体(主要是CO2)的排放情况,指出能源消耗是造成钢铁工业CO2排放的主要原因。在对比两类典型钢铁生产流程的CO2排放情况的基础上,深入分析了钢铁工业的能源结构及不同流程中原燃料来源结构对CO2排放的影响;最后对新一代钢铁制造流程的CO2排放进行了估算。Climate change caused by the GHG emission has become one important issue globally.The GHG emission,which refers to CO2 primarily,in the Chinese iron and steel industry is introduced.It is pointed out that energy consumption is the main reason to result the CO2 emission for steel industry.The impact of energy structures in the typical steel manufacturing process on the CO2 emission is analyzed,based on comparing between two typical production processes,and the impact of different sources and structures of raw material and fuels in the different processes on the CO2 emission is also discussed.Finally,the CO2 emission of the new generation steel manufacturing process has been estimated.
