Abstract
A method for determining a heating line for bending a steel plate includes the steps of: placing a virtual pattern on a virtual plate; rolling the plate along a frame line from a reference position to contact the plate at two points on the plate; rolling the steel plate back to the reference position; obtaining straight lines connecting the contact points; determining a heating point relative to a reference point; repeating the same steps while contacting the contact points on a reference point side; drawing straight lines from a certain heating point on a certain line to heating points on other lines; examining the degree of parallelism between each straight line and a roller line; grouping the relevant heating points as the same group; and connecting the heating points of the same group by a straight line or a curve.
