Abstract

PURPOSE: To easily manufacture at high yield the flat shape product possessing the breadth changing along the longitudinal direction, by changing the thickness of the rolled material along the longitudinal direction, and next, by feeding the 90° turned material for carrying out the broadside rolling pass.
CONSTITUTION: The rectangular slab is obtained by rolling the slab. Next, in the final roll forming pass, the controlling system for the rolling work is employed for changing the roll gap in carrying out the rolling work while giving the specified taper shape to the section of the slab along its longitudinal direction, and giving the correction to the rolling reduction correspondingly to the spreading ratio; hereby, the specified sectional shape is obtained. Further, this material is turned by 90° and is subjected to the broadside rolling pass for obtaining the specified breadth. When this broadside rolling pass comes to the end point, the material possesses the specified taper and breadth, besides, the effect of the rolling pass with the corrected rolling reduction gives the rolled material the good breadth size. Next, the material is turned by 90°, and is subjected to the ordinary rolling pass, and then, the rolled product possessing the specified thickness and the taper shape with breadth changing along the longitudinal direction is obtained.
