圆管感应加热工件内电参数的计算

The calculating of electric parameters for induction heating of round pipe workpieces

把圆管感应加热时的电磁场看成是一维轴对称场,解得各场量,应用坡印亭向量从理论上导出了圆管感应加热时各电参数的理论计算公式,并借助于计算机获取了精确的计算系数值,为圆管感应加热的设计计算提供了准确、实用的方法。

The induction field in the round pipe during the induction heating can be regarded as an one dimension and axial symmetry field. Judging the magnitude solutions of that field and using the Poynting vector, the calculating formulae of electric parameters of said induction heating could be determined theoretically. With the aid of a computer the values of coefficients in the formulae have been obtained accuratelly. Therefore an appropriate method for designing and calculating of round pipe induction heating has been provided.
