摘要(Abstract)：

针对非珠光体层十分突出的高碳钢重载车轮,基于MSC.Marc和Thermal Prophet建立了踏面淬火(CVQ)与复合淬火(CPQ)的有限元数值模型,对比分析了两种冷却方式对车轮热处理温度场及组织性能的影响,并进行了实物验证。结果表明:模拟计算结果与实物验证结果吻合较好。自踏面向下,CVQ车轮的温度梯度、组织梯度及强硬度梯度显著,其踏面近表层的非珠光体层深约15 mm,为马氏体(M)、贝氏体(B)及其混合组织。CPQ工艺能有效控制或基本消除非珠光体层,优化了轮辋全截面显微组织,强硬度梯度合理,并在踏面次表层一定深度范围内形成局部的强硬度极大值区,使该区域的强硬度较CVQ车轮略有提高。
