The specific work is as follows:
- The process analysis of typical sand mold casting process is carried out, and the energy, materials and unexpected input and output of sand mold casting process are analyzed. According to the characteristics of sand mold casting process parameters, the process parameters and of sand mold casting are classified, and the specific carbon sources of the process are classified based on the different properties of the parameters.
- The carbon source model of sand casting process is established, and the calculation range of carbon emission of each carbon source and the calculation method of subdivided carbon source are specified.
- Based on the process parameters, the carbon emission calculation model of sand casting is established. A low carbon optimization strategy of sand casting process parameters based on genetic algorithm is proposed.
- Under certain sand casting process conditions, the process parameter design scheme is put forward, and the carbon emission is estimated.
