摘　　要：轮胎模具再制造是实现“碳达峰、碳中和”目标的有效方式之一。文章基于生命周期评价理论,系统地分析轮胎模具再制造过程中的碳排放,建立了基于物料流、能量流、废弃物流的再制造过程碳排放量化模型,得出了生命周期各阶段的碳排放;选取轮胎模具再制造过程中的零件侧板,改造焊补、车修、铣修、刻字等工艺,计算改造过程的生命周期碳排放,针对碳排放占比较高的项目提出通过设备优化和改进加工工艺方案来降低碳排放。结果表明:采用生命周期理论能够高效地测算各阶段的设备、物料、废弃物的碳排放;侧板再制造过程中物料和能源的碳排放占比分别为75.3%和18.3%;改造工艺后,其碳排放分别下降了10.7%和6.1%,节能减碳效果显著。Remanufacturing tire molds emerges as a pivotal strategy in the pursuit of“peak carbon and carbon neutrality”objectives.Based on the life cycle assessment theory,this paper systematically examines the carbon emissions throughout the tire mold remanufacturing process.A quantitative model of carbon emissions based on material flow,energy flow and waste flow is established,and the carbon emission of equipment,material and waste in each stage is obtained.Focusing on the sidewall plate as a representative component various processes such as welding repair,turning repair,milling repair and lettering are employed.The life cycle carbon emissions of the remanufacturing process are then computed.For the prospect with high carbon emissions,it is proposed to reduce carbon emissions by optimizing equipment and improving processing technology.The results indicate that the carbon emission of equipment,materials and wastes at each stage can be efficiently obtained by using the life cycle theory;the carbon emissions of materials and energy in the sidewall remanufacturing process accounted for 75.3%and 18.3%respectively;after the transformation of the process,its carbon emissions decreased by 10.7%and 6.1%respectively,signifying a substantial impact on energy conservation and carbon reduction.
