Line heating system for initial imposed deformation condition and method thereof

摘要

line heating method and apparatus considering the force deformation of steel is provided. Line Heating method considering the deformation force of the steel sheet according to the present invention, measuring a steel sheet that is currently processing, and inputting a measurement of the shape information and the design shape of the steel plate that is currently processing, and constraining force of the steel strip calculating the deformed position, comprising forcing the deformation amount calculated for each of the steel sheet according to the constrained position of the steel sheet, the calculated force and the set heating step to set the heating line of the line position and strength of the steel sheet according to each of the strain including the step of machining a curved surface according to the position and intensity, plate more efficiently than by carrying out the line heating with a small number of the heating wire are not taken into account deformation forces line heating of the steel sheet may be hot worked.
