Line heating-induced permanent deformation behavior of a SS400 thick plate has been investigated through both numerical analysis and experimental testing by applying high frequency induction as a heat source after generating dual-curvature by secondary line heating. Electromagnetic-thermal-structural coupling numerical analysis was first utilized for the prediction of temperature distribution and subsequent permanent deformation over the SS400 carbon steel plate. Also experimental line heating was carried out to validate the feasibility of the numerical analysis by applying newly designed laboratory-scale high frequency (HF) induction heating (IH) equipment. Both the numerical and experimental results indicate that depth and width of the heat affected zone (HAZ), generated by the interaction between I-IF induction heat source and upper surface of the workpiece, tend to increase with the increase in the input power. Also the numerically calculated depth of HAZ coincides well with experimentally obtained HAZ profiles. Permanent vertical deformation is increased with an increase in the input power regardless of both concave and saddle-type doubly curved plates. Transverse curvature determined in both simulation and experiment were investigated, and the results indicate that the transverse curvature after HF IH achieves good agreements between the FE analysis and experimental measurement regardless of input power and shape of plate, indicating the effectiveness of the eco-friendly designed HF IH-based line heating apparatus established in KIMS.
