摘要(Abstract)：

不同部位差异化性能的达标是宽厚板轧机支承辊制造的技术关键与难点，而奥氏体化温度是决定支承辊各部位最终性能的核心工艺参数。采用实际工况热物理模拟、显微组织表征及力学性能测试相结合的方法，研究了奥氏体化温度对宽厚板轧机支承辊显微组织演变与力学性能的影响规律。结果表明：基于奥氏体化温度对钢中碳化物溶解程度的影响特性，可以调控宽厚板轧机支承辊用钢的奥氏体晶粒尺寸、显微组织形态及力学性能分布；对于支承辊整体的热处理工艺(即预备热处理),最适宜的奥氏体化温度区间为840～870℃,藉此形成的大量未溶碳化物颗粒可作为珠光体渗碳体的形核核心，促进粒状珠光体组织的形成，从而确保辊身心部具有良好的强韧性；对于支承辊表面的热处理工艺(即最终热处理),适宜的奥氏体化温度区间为870～900℃,藉此可使碳及合金元素充分固溶并有效抑制奥氏体晶粒长大，从而确保淬火后辊身表层获得高硬度的马氏体组织。
