The analysis of sand casting process is the basis for judging the composition of various material flow, energy flow and waste logistics in sand casting process. Material flow, energy flow and waste logistics contain various carbon sources, which are affected by the process scheme and process parameter design. Therefore, material flow, energy flow and waste logistics are the basis for analyzing the composition of carbon sources. The sand casting process and are analyzed, and the direction of energy and material waste logistics in the sand casting process are analyzed.
According to the different properties of casting process parameters of sand casting, the casting process parameters of sand casting are divided into independent process parameters of sand casting, coupling process parameters of sand casting and inherent process parameters of sand casting. On this basis, combined with the specific carbon source composition, the corresponding carbon source emission model can be established to calculate the carbon emission of carbon source in the process design section of sand casting. Moreover, according to the carbon emission model, the corresponding low-carbon optimization method can be proposed to reduce the carbon emission of the actual process through the optimization of the corresponding sand casting process parameters in the sand casting process design stage.
