摘　　要：将能耗指标分解模型应用在某厂的主要生产流程中,通过对吨钢综合能耗的分解计算,从物质流和能量流的角度来评价分析该厂的能耗现状,挖掘节能潜力。分析发现该厂高炉和烧结工序的产品结构因素是限制吨钢综合能耗进一步下降的瓶颈环节。结合生产实际,提出了提高转炉废钢比、改善高炉燃料结构、降低烧结机漏风率等较有针对性的措施,并量化了转炉废钢比及烧结机漏风率与能耗之间的关系,以期为该厂未来的节能工作提供可行的思路和方向。The decomposition model of energy consumption index was applied in the main-process stream to decompose the energy consumption per ton steel,so that influence of both energy and material flew on the total index could be analyzed.It is found that,the production structure of blast furnace and sinter processes were the bottlenecks.And the suggestions were raised as increasing the rate of scrap steel and decreasing the air leakage rate would be helpful for declining the energy consumption per ton steel.Additionally,how much energy could be saved exactly was quantified to direct this plant's energy saving in the future.
