Abstract

In this paper, a kind of inductive hot correction coil for sheet welding deformation is proposed. In this scheme, COMSOL Multiphysics simulation software is mainly used to analyze the electromagnetic - stress coupling of the thin steel plate with size parameter of 1000 mm×600 mm×6 mm, so as to explore the influence of different coil forms on the temperature field and correction effect. The results show that for the longitudinal magnetic flux rectangular coil, the temperature field distribution is uniform, but the temperature rise efficiency is lower than that of the transverse magnetic flux circular coil, and the clamping of the workpiece is inconvenient. Under the action of the offset longitudinal magnetic flux rectangular coils and transverse magnetic flux rectangular coils, the temperature field distribution is not uniform, and the deformation trend of the workpiece cannot achieve the purpose of correcting the welding deformation. Under the action of transverse magnetic flux circular coil, the workpiece's temperature rise rate is fast, the temperature distribution is even, the cooling process is gentle, and the correction effect is good. Considering the thermal efficiency of the coil, the effect of correction and the convenience of correcting the large-size sheet, the transverse magnetic flux circular coil was finally determined to be suitable for the deformation correction of the sheet after welding.
