Abstract

The present invention provides a line-heating method which reflects the forced deformation of a steel sheet, and to a system thereof. The line-heating method according to the present invention comprises the steps of: measuring the steel sheet currently being processed, and inputting information on the designed shape of the steel sheet and the measured shape of the steel sheet currently being processed; calculating the restricted and forced deformation position of the steel sheet; calculating the forced angular deformation of the steel sheet in accordance with the restricted position of the steel sheet; setting the position and intensity of the heating wire of the steel sheet in accordance with the calculated forced angular deformation; and processing a curved surface in accordance with the position and intensity of the heating wire set in the previous step. The method of the present invention performs line heating by using less heating wires than methods which do not consider the forced deformation of steel sheet, thereby performing hot working on the steel sheet with improved efficiency.
