Aiming at the problem of induction heating forming of steel plates, the major influencing factorsof steel induction heating are analyzed through orthogonal experiments and turn out to be heating rate andair gap; the relationship between the two parameters and deformation of plates is explored with the methodof numerical simulation, which shows that the heat rate and air gap affect the heating depth and have a sig-nificant impact on the value of transverse shrinkage, transverse angular distortion, and vertical displace-ment. Finally, the regression formula is derived based on numerical samples, and the relative error betweenthe theoretical result and the experiment value is within permissible range, which successfully validates theregression formula.
