摘要(Abstract)：

利用有限元软件ANSYS建立规格为?586 mm×72 mm的A335P92钢厚壁管焊接接头感应加热的电磁-热耦合数值模型,通过开发自动热追踪算法程序计算并分析钢管焊接接头局部焊后热处理内外壁温差以及截面温度场分布。对模型进行验证后,进一步分析了加热宽度、线圈匝数、频率、内壁换热系数对管道局部焊后热处理温度场的影响规律。结果表明,感应加热具有明显的集肤效应,在居里点出现明显的温度波动;加热宽度(线圈布置宽度)大于600 mm时,改变线圈匝数(n=10～30)、电磁频率(H=1000～3000 Hz)对管道内外壁温差影响不明显;内壁换热系数是管道内外壁温差的关键影响因素。
