THE ANALYSIS OF THE RELATIONSHIP BETWEEN IRON RESOURCE EFFICIENCY OF STEEL PRODUCTION PROCESS AND OF ITS UNIT PROCESS
钢铁生产流程铁资源效率与工序铁资源效率关系的分析

Based on the concept of iron-flow diagram of steel production process, a expression of relationship between iron resource efficiencies in steel production process and unit process has been derived. By using the data of a steel plant, the above relationship was analyzed, and the influence of iron resource efficiency of unit process on iron resource efficiency of steel production process was discussed as examples.
