Line heating (LH) is a method of forming curved thick plates. Residual deformation of a steel plate is obtained by applying heat to the plate. Heat transfer analysis between a torch and the steel plate is essential to control the residual deformation of the steel plate in LH. This paper presents an analysis of the heat transfer during LH. The mechanism of combustion flame from a torch is simplified as an impinging gas jet. A turbulent thermal fluid flow analysis is employed to determine the temperature field. Results of numerical and experimental approaches are compared to verify the proposed analysis procedure. The parametric analysis shows that the nozzle diameter and the tip clearance are the important factors of the heat flux induced by the flame.
