钢铁行业工序能耗分析及节能发展方向探讨

Energy consumption analysis and energy saving direction discussion of iron and steel industry process

基于钢铁行业各工序平均能耗以及钢铁行业原燃料结构,对钢铁行业焦化、烧结、炼铁、炼钢、轧钢等工序的原燃料结构、能耗特点和节能技术进行了分析,在此基础上对钢铁行业节能发展的重点进行了讨论,并针对炼铁工序焦比、煤气利用率、二次能源回收等重点环节的发展方向进行了探讨,对于钢铁行业的节能降耗有着较大的实际意义。

According to the average procedure energy consumption and crude fuel structure of iron and steel industry,the crude fuel structure,energy consumption characteristic and energy saving technology of the processes including coking,sintering,iron making,steelmaking and rolling were analyzed.On this basis,the key points of the energy saving development of iron and steel industry were discussed.Then the development direction of the key ＇aspects including the coke ratio of iron making process,gas utilization rate,secondary energy recovery and etc were investigated, which has a great practical significance to iron and steel industry.
