摘要

Under the conditions of economic marketization, the evaluation mechanism without considering the environmental costs is not conducive to comprehensively and objectively understand the composition of product costs, and fails to achieve the purpose of resource optimization. The comprehensive costs of the ironmaking process is affected by multiple factors of energy, environment and economy. Based on the combination of the environmental cost obtained by the life cycle assessment method and the exergoeconomic theory, an exergoeconomic evaluation model of the ironmaking process considering the environmental cost is created and realizes the comprehensive evaluation of the cost of the ironmaking process. Its serious environmental impact categories are metal depletion, freshwater eutrophication, marine ecotoxicity, natural land transformation and freshwater ecotoxicity. The law of comprehensive cost formation considering energy environment in ironmaking process is traced. Sinter, pellet and pulverized coal are the three key factors affecting the cost of ironmaking. After considering the environmental impact, the cost ratio of sinter and pulverized coal increases by 10.85% and 9.31% respectively, while the ratio of pellet has little change. This study can help steel enterprises to analyze the production costs of each unit after considering the overall environmental impact, accurately locate the implementation points of energy conservation and emission reduction, and provide ideas and basis for scientifically guiding the sustainable development of enterprises.
