Abstract

The invention discloses an evaluation method for a global warming influence potential value of an electrode product for metallurgy. The evaluation method comprises the following steps: S1, defining a target and an evaluation range; s2, constructing a life cycle list; s3, processing the multi-output flow by a physical distribution method: distributing the generated environmental load according to the physical attribute proportion of mass, energy or heat value and the like between the main product and the by-product for the unit process with the multi-output condition, and forming a life cycle list of the metallurgical electrode product based on the functional unit; s4, environmental influence evaluation; and S5, result interpretation and optimization suggestion. The method has the advantages that the full-life-cycle environmental influence of the metallurgical electrode product is quantified comprehensively and objectively, a solid theoretical support is provided for upgrading of a production process and carbon and emission reduction in the whole process, and meanwhile, a powerful basis is provided for green attribute authentication and market promotion of the product.
