摘要： 把大型钢铁企业的生产系统分解为相互关联的物质流动和能量流动过程两部分.针对其中的物质流动过程,构造从天然铁矿石(或废钢)到钢铁产品生产过程的物质流图,并建立含铁物料流动过程的铁流模型;针对能量流动过程,构造从一次能源到二次能源产品的生产、转换和使用直至废气排放的能量流图,并建立钢铁企业能量流模型;考虑物质流和能量流的相互关联和制约,建立两者的耦合模型.基于模型,讨论了钢铁生产过程中物质流变化、能量流变化及其相互作用对企业能耗及资源效率、能源效率的影响,指出了提高资源效率、能源效率的努力方向.

Abstract: The whole production process in iron and steel industry is decomposed correlatively into two parts: the material flow process and energy flow process. A material flow chart is given from crude iron ore or scrap to final products, with a model developed showing the flow process of iron-bearing materials. An energy flow chart is also given from primary to secondary energy source and then to waste gas emission through consumption and transformation, with a model developed showing energy flow in iron and steel industry. A coupling model for both material flow and energy flow is thus developed considering the interaction and correlation between them. The influences of both flows on the energy intensity, resource efficiency and energy efficiency in the iron and steel industry are discussed.
