One of the methods for shaping double-curved metallic plates is the line heating process. In this process, they are gradually shaped by heating the plates in the direction of predetermined lines. In the past, mainly gas torches have been used as heating sources. Since the heat flux of the source should be controlled for accurate control of plate deformation during the process and this is not easy with the torch, one of the suitable alternatives is the induction coil as a heating source. In this research, an experimental evaluation of the linear heating induction process of steel plates has been dealt with and studied. Considering the cost of the experimental tests, they were designed by Taguchi method after selecting the effective variables. Thickness of the plate, intensity of the current passed through the coil and velocity of the coil were the studied variables. Deflection and angular distortion of the plate are also considered as the process outputs. Among these variables, thickness of the plate has the greatest impact on the deflection and angular distortion of the plate. Intensity of the current is important in the second order. In the intended range for coil velocity, no significant changes were made in their amount while confirming the impact of this variable on process outputs.
