Abstract
PURPOSE: To improve the asymmetry of the tip and tail of the material along the rolling direction, and to improve the product yield through the skew rolling pass, by executing even times of skew rolling passes with approximately uniform draft percentage before the broadside rolling is finished.
CONSTITUTION: This method is for improving the draft schedule of the conventional skew rolling method; from the result of experiments, it is cleared that the plane shape of material after the rolling work is determined by the shape of material at the point of completion of the broadside rolling pass. Accordingly, even times of skew rolling passes with almost uniform draft percentage (the deviation of the draft percentage is limited to ±10% or less) are carried out before completing the broadside rolling pass; hereby, the asymmetry in the tip and tail shapes is improved, and the product yield is improved. By the uneven times of skew rolling passes, this asymmetry becomes large.
