摘　　要：针对设定的国产交流传动机车车轮钢材料，在实验室中分别研究了淬火加热温度、淬火冷却速度和回火温度对车轮材料组织与性能的影响，提出了最优化的车轮热处理工艺参数，并以此参数为基础进行了车轮工业化试制。对试制出的车轮样品进行全面解剖分析的结果表明试制车轮各项力学性能均达到了预设目标要求，提出的热处理工艺参数合理有效，具备可操作性。Aiming at steel materials of domestic AC drive locomotive wheels, respectively, in the laboratory to study the effects quenching temperature, quenching and tempering temperature on the cooling rate of the material microstructure and properties of the wheel, the wheel is proposed to optimize the process parameters of heat treatment and this argument as the basis for the wheels of industrializa- tion trial. The results of the trial out of the wheel full anatomical analysis of the samples showed that the mechanical properties of prototype wheels have reached the preset objectives and requirements, reasonable and effective heat treatment process parameters pro posed, with maneuverability.
