摘　　要：针对难变形合金的加工成形方法进行研究,运用Deform-3D有限元软件与SolidWorks三维机械设计软件建立了二辊轧机轧辊的电磁感应加热模型,通过模拟不同电流密度、电源频率和轧辊转速下轧辊的电磁感应加热过程以及不同冷却条件下轧辊的在线感应加热过程,分析了轧辊温度场的变化规律,最终得到合适的轧辊电磁感应加热参数。制作了专属轧辊的感应加热线圈,根据模拟中所得出的参数进行了轧辊电磁感应加热实验验证,成功将轧辊加热至600℃以上,辊面温度实测值与计算值吻合良好,证明了所建立模型的准确性,有望在800℃以下实现TiAl合金的近等温轧制。The processing method of hard deformation alloy was studied and the finite element software Deform-3 D and three-dimensional mechanical design software SolidWorks were used to establish the electromagnetic induction heating model for roll of two-high rolling mill.The variation of temperature field of roll was analyzed by simulating electromagnetic induction heating process of roll with different current densities,power frequencies and roll speeds,as well as the on-line induction heating process under different cooling conditions,and finally the appropriate parameters of electromagnetic induction heating were obtained.The special induction heating coil for the roll was manufactured and the electromagnetic induction heating experiment verification of roll was carried out with the parameters obtained from the simulation,and the roll was successfully heated to above 600 ℃.The measured temperature values of roll surface are fit well with the calculated values,which proves the accuracy of the established model.It is expected to realize near isothermal rolling of TiAl alloy below 800 ℃.
