Abstract: To select the benchmark of low carbon casting scientifically and to identify the quantitative carbon emission targets,a low carbon benchmarking modeling of sand casting based on process carbon sources was proposed.Through analyzing the feature of sand casting production processes,the carbon emission calculation method of sand casting based on process carbon sources was constructed.The similarity calculation model of low carbon benchmarking was established by considering influence of process route and process carbon sources similarity.The benchmarking process modules carbon emission model,benchmarking modules production capacity model and benchmarking potential model of low carbon casing were built,and the quantitative description method of benchmarking potential method was realized.The low carbon benchmarking similarity and benchmarking potential value were calculated to provide support for realizing the effective low carbon of energy-saving and emission-reduction for sand casting enterprises.
