Abstract：To quantitative describing the efficiency of material transformation and energy conversion and distinguish the effects of material transformation and energy conversion of different manufacturing flow in steel production,based on the material transformation and energy conversion characteristic analysis of the main manufacturing flow of ironmaking-steelmaking-continuous casting-hot rolling and manufacturing unit of stage/device,a multi-scale evaluation method is proposed,which takes the flow material conversion rate and flow energy dissipation rate as manufacturing flow evaluation indexes,and the process material conversion rate and process energy dissipation rate as manufacturing units evaluation indexes. Some actual production data of steelmaking plants are adopted to calculate the efficiency of material transformation and energy conversion. It is found that the material transformation and energy conversion of the same type of steel varies with different production flow,and different manufacturing units and their cohesive relationship influence the material transformation and energy conversion of the manufacturing flow. The results show that the evaluation method can provide guidance for the collaborative optimization of material and energy in the production control.
