Abstract
PURPOSE: To efficiently manufacture the thick plate with various plane shapes, by preparing the rolled material with thickness changing in the rolling direction depending on the assortment design for plural thick plates, and by 90 degree turning this material and forming it into the plane shape with the dimension changing from the middle point to the tip.
CONSTITUTION: The rolling reduction is changed from the middle point during the rolling work for the forming pass of rolling in the direction of arrow L, in order to prepare the rolled material 14 with the changed thickness, that is thickness t1 for length L1 and thickness t2 for length L1. After that, this rolled material 14 is 90 degree turned and is subjected to the broadside rolling pass (in the direction of arrow W) so as to obtain the previously calculated spread and the specified thickness, and the rolled material 16 is prepared. This material 16 is again 90 degree turned, and is subjected to the forming pass to form the rolled material 18 with different breadths; this material 18 is cut into plural products 20 and 22. The dimension of the rolled material 14 necessary for obtaining the rolled material 18 is previously determined by calculation. As a result, the crop loss is greatly reduced, and the yield is improved.
