According to the three carbon source calculation models based on three types of sand casting process parameters, the total carbon emission model based on sand casting process parameters can be obtained by integrating the formulas as follows:
Through three kinds of sand casting process parameters, the calculation models of material carbon emission, energy carbon emission and unexpected carbon emission can be established, and the effects of different process parameters on different carbon sources can also be analyzed. This is very beneficial to the process design of sand mold casting in the design stage, and the optimization of energy conservation and emission reduction can be carried out in the process design stage of sand mold casting.
