[0004] However, the above carbon emission calculation methods are difficult to estimate and reduce carbon emission in the casting process design stage
In order to obtain a low-carbon sand casting process in the sand casting process design stage, carbon emissions must be calculated at this stage, but there is still a lack of an effective method for accurately estimating carbon emissions in the casting process design stage

The invention discloses a sand mold casting carbon emission calculation method based on process design parameters. The calculation method is divided into three parts: calculating carbon emission of sand mold casting independent process design parameter, calculating carbon emission of sand mold casting coupling process design parameter, and calculating carbon emission of sand mold casting inherentproperty process design parameter. The last three parts sum to obtain carbon emission of sand mold casting based on process design parameter. The invention can calculate the carbon emission of the sand mold casting product through the design parameters of the sand mold casting process in the product design stage. And each sub-item of carbon emissions can be visually displayed so that sand castingprocess can be optimized and improved before production in order to ultimately reduce carbon emissions and reduce energy consumption which has certain theoretical and practical significance for the sand casting industry.
Description
【Technical field】 [0001] The invention relates to the technical field of sand casting, in particular to the technical field of a sand casting carbon emission calculation method based on process design parameters. 【Background technique】 [0002] Studies have shown that nearly one-third of the world's energy consumption and 36% of carbon dioxide emissions come from manufacturing. Among them, as a basic method of manufacturing, sand casting has more serious environmental problems than other casting methods. A typical modern sand casting process contains many different stages such as melting, alloying, molding, pouring, solidification and finishing. Casting is also one of the most energy-intensive manufacturing processes, where the metal melting step consumes more than half of the total energy (Pagone, 2018; Salonitis et al., 2017). During the casting process, foundry sand can be recycled and reused. When foundry sand loses its properties and is not suitable for further use f...
