Curve transition method of variable thickness strip transition area

The invention discloses a curve transition method of a variable thickness strip transition area, and relates to a variable thickness strip rolling technology. According to the method, the curve transition of the transition area is conducted through a double power function curve with the same front half power exponent and the rear half power exponent and a double power function curve with different front half power exponent and the rear half power exponent. The curve of the transition area has the advantages of being continuous and smooth, adjustable in shape, and capable of eliminating rolling force mutation in transition area rolling and reducing the maximum rolling force. The curve transition method of the variable thickness strip transition area is significant for rolling production of the variable thickness strip and rolling machine maintenance.
