Abstract


The purpose of this study is in the current serious shortage of resources, severe environmental degradation, increasingly stringent national environmental policy in the case, enterprise systems, how to achieve energy reduction targets to further improve their adaptability and international competitiveness, resource recycling and sustainable development of enterprises. Substance flow analysis (SFA) is in a country or a region within a specific substance (such as aluminum, copper, etc.), or combination of substances (eg heavy metals) conduct an effective means of industrial metabolism studies. Material flow analysis aims to find savings of natural resources, ways to improve the environment in order to promote industrial development direction of transformation to a sustainable system. Good material flow analysis, is it possible to raise resources and environmental aspects of the recommendations for policy makers. Through the steel production process material flow analysis to identify the entire production process flow of material flow can be found in the whole process, the material flow of critical parts, the \to ensure smooth production; through the steel production process energy flow analysis and simulation, you can figure out the flow of energy flow, and further found that the main energy consumption point for energy conservation and lay a good foundation; the material and energy flows coupling model, can dynamically reflect the changes in the flow of energy along with material flow situation for the realization of energy to find a breakthrough to achieve the overall system optimization, rational organization of production, resources and energy to achieve sustainable development. In this paper, iron and steel production processes on the basis of detailed research, the establishment of steel production processes in various situations of material and energy flow system dynamics model and different conditions for different models of the dynamic simulation study to simulate various circumstances logistics and energy flow relationships, and constraints affecting the relationship between factors, to achieve system optimization, identify ways to improve the breakthrough to provide theoretical and practical guidance. System dynamics theory, create a regional system of steel product life cycle material flow model, and different modes of production and regional scenarios steel product life cycle material flow systems are discussed in detail, dynamic display of the iron flow in the system The current situation, particularly in the different production modes, the amount of recycled scrap and iron ore investment changes; introducing the concept of resource efficiency, analyze three different modes of production and iron resource efficiency scenarios are different. For the country to develop on steel products recycling and efficient use of policy decision-making basis.
