Iron And Steel Production Processes, System Dynamics Modeling And Dynamic Simulation

The purpose of this research is how does the enterprise system realize the energy conservation to reduce a row of goal day by day, further enhances own compatibility and international competition ability, realizes the resources cyclic utilization and enterprise's sustainable development under the grievous situation of energy crisis,resources shortage, environment pollution and the increasing strict national policy。Substance flow analysis (SFA) is an efective tool for studying the industrial metabolism of specific substances (e.g. aluminum, copper) or group of substances (e.g heavy metals) on a certain spartial scale, for example, on the scale of a country, a region or a firm. The purpose of SFA is looking for the potentials and measures of resource conservation and environment protection, and encouraging industrial system to meet the requirement of sustainabled evelopment. Thus, the proposals offered in SFA can be of assistance to decision makers.Through to the steel production material flow analysis, discovers the entire production process material class the mobility status, may discover that in the entire flow, the material class's essential spot, "the bottleneck" is, is advantageous further carries on the optimization to us to system's flow of matter, guarantees the production smooth advance; Through to the steel production process energy flux's analysis simulation, may make clear the energy flow\\ mobility status, further discovered that the energy the main consumption spot, reduces the platoon for the energy conservation to build the good foundation; Carries on the coupling the material class and the energy flux model, might the dynamic response energy flow along with the material class change situation, to realize the energy conservation to find the breach, realized overall system's optimization, the reasonable organization production, realized the resources and the energy sustainable development.Take the systems dynamics theory as the foundation, founded the region steel and iron product life cycle system's material class model, and the region steel and iron product life cycle system's material class carried on the detailed discussion to under the different production pattern and the scene, the tendency had demonstrated the flowing of molten iron in system mobility status, specially under the different production pattern, recycled the scrap steel and the investment iron ore quantity change situation; The introduction resources efficiency's concept, analyzes under three kind of different production patterns and the scene the hard resources efficiency difference.
