基于碳排放的砂型铸造能源、设备和成本的研究

Research on energy sources,equipment and costs in sand casting based on carbon emissions

【目的】为促进铸造行业的可持续发展,研究砂型铸造中使用不同能源和设备对碳排放和成本的影响。【方法】首先根据砂型铸造的生产过程特点建立碳排放模型和成本模型;然后分别在不同熔炼量和产品条件下对感应电炉、燃焦冲天炉、天然气冲天炉和天然气回转炉的碳排放量和生产成本进行计算;最后对4种熔炼炉的碳排放量和生产成本进行总结分析。【结果】在不同熔炼量和产品条件下,与传统感应电炉相比,使用天然气冲天炉可以使铸造熔炼阶段的碳排放量和成本分别降低73.29%和59.26%。【结论】本研究结果可为铸造行业的进一步转型升级和可持续发展提供理论参考。

[Objective]To promote the sustainable development of the foundry industry,the impact of using different energy sources and equipment was investigated on carbon emissions and costs in sand casting.[Method]First,the models of carbon emissions and costs were established according to the characteristics of the sand casting production process;then,the carbon emissions and production costs of induction furnaces,coke-fired cupolas,natural gas-fired cupolas,and natural gas rotary furnaces were calculated under different melting capacities and product conditions;finally,a summary analysis of the carbon emissions and production costs for the four types of melting furnaces was conducted.[Result]Under varying melting capacities and product conditions,compared to traditional induction furnaces,the use of natural gas-fired cupolas can reduce carbon emissions and costs during the melting stage of casting by 73.29%and 59.26%,respectively.[Conclusion]The findings of this study provide a theoretical reference for the further transformation,upgrading,and sustainable development of the foundry industry.
