摘　　要：本文应用《冶金流程工程学》"三大功能"理论,在解析钢铁制造流程能源转化过程的基础上,分析了钢铁企业能源成本的构成及节能增效的潜力,分析了钢铁流程能源转换的功能特色及价值优势,指出忽视能源流的"矢量"特征及能源质量价值是系统能效低的重要拫源。认为钢铁流程"能源转换功能"价值有待深度开发,通过工序、行业等跨界拓展优化可在更高层次上实现钢铁企业的流程价值,也是实现行业绿色转型发展的重要手段。现阶段,以系统优化方法,实施顶层设计,制定能源系统优化整体解决方案,挖掘流程用能极限及提高余热余能自发电比例应成为提升钢铁企业系统能效的重要着力点;构建新的"煤铁化工"新平台,以焦炉煤气、高炉煤气、转炉煤气的化工合成升值利用为核心,实现伴生煤气资源化工合成的物质转换是钢铁流程巨大的价值潜力所在。In this paper,the theory of“three functions”in the Metallurgical Process Engineering is applied,on the basis of analyzing the process of energy transformation in iron and steel manufacturing process,the compositionof energy cost and the potential of energy saving and efficiency in iron and steel enterprises were analyzed,and the functional characteristics and value advantage of energy conversion in iron and steel process are analyzed.This paper pointed out that energy flow of“vector”characteristics and quality of energy value is an importantsource under the low system efficiency.This paper considers that the value of energy conversion function in ironand steel process should be further developed,and the cross-border expansion within the scope of the process andother industries can not only optimize the process of iron and steel enterprises value at a higher level,but also animportant means to realize the development of green transformation of the industry.At this stage,the system optimizationmethod,the implementation of the top-level design,the formulation of energy system optimization solutions,mining the energy consumption limit of the process,and improvement the residual heat energy self generationratio should be an important focus to enhance the system energy efficiency of the steel enterprise.To build anew platform of the“iron and coal chemical industry”for chemical synthesis of blast furnace gas,coke oven gas,converter gas utilization appreciation as the core,to realize the associated gas resources chemical substance conversionare the core value of iron and steel process huge potential.
