A low carbon process design method of sand casting based on process design parameters

Abstract

Abstract The widespread use of sand casting technology has brought tremendous pressure on the environment due to its energy consumption, waste discharge, and process related carbon emissions. A plan should begin at the design phase of the casting, in order to achieve low carbon sand castings or sand castings with low greenhouse gas emissions. Accurate prediction of carbon emission in sand casting is the basis for carbon emission reduction. To calculate and reduce carbon emission of sand castings during the sand casting process design phase, a low carbon process design method of sand casting based on process design parameters is proposed. The process design of sand casting includes various parameters. Three types of sand casting carbon source model were built by three categories of process design parameters analysis of sand mold casting. so as to predict the carbon emission of sand mold casting. The feasibility of the proposed method to estimating the carbon emission in the process design stage was validated by using a practical example. Through the comparison of the two process design schemes based on this method, it can be proved that carbon emissions have decreased significantly. Moreover, we can know the amount of carbon emissions from each type of carbon source can be predicted. A low carbon sand casting process during the sand casting process design phase can be created by this method. The optimization of process design parameters was useful to the reduce carbon emissions of the sand casting and benefited to achieve the aim of reach sustainable manufacturing.
