摘要(Abstract)：

针对目前无缝钢管采用外表面喷射与内表面轴向喷射的浸淬淬火方式,利用ANSYS软件对钢管浸淬温度场进行数值模拟。分析了部分浸入与全浸入淬火冷却各因素对温度场冷却均匀性的影响,这些因素包括喷射速度、钢管的旋转速度及部分浸入浸润角等。结果表明:部分浸入式淬火中,内外表面均不喷水,浸润角为180°~270°时,内外表面冷却较均匀且冷却速度较浸润角为0°~180°时快;外表面不喷射,内表面轴向喷射时,内喷速为3 m/s时,内外表面冷却较均匀;钢管的旋转速度应不低于60r·min-1时,钢管径向冷却均匀性较好。全浸入式淬火中,内喷速度为8 m/s,外喷速度为6 m/s和内喷速度为10 m/s,外喷速度为7 m/s时,内外表面冷却较均匀;钢管的旋转速度越大,内外表面的温度差波动越小,冷却均匀性越好,故钢管旋转速度应不低于60 r·min-1,但考虑到能耗及稳定性问题,钢管旋转速度则应不高于90 r·min-1。
