Abstract

PURPOSE:To correct tapered shapes in good yields by subjecting a tapered steel material of successively varying widths to taper rolling so as to increase the thickness gradually from the broad side toward the narrow side then turning the rolled material at a right angle and rolling the same with horizontal rolls. CONSTITUTION:After a slab 1 of width W0B on a broad side, width W0T on a narrow side, length L0, and thickness H0 is subjected to ordinary rolling to a thickness H, the slab is subjected to tapered rolling so as to increase the thickness gradually from the broad side toward the narrow side under regulated roll gaps, the upward and downward moving speeds of roll screw-down mechanisms and the number of revolutions of rolls, whereby the slab is rolled to a rolled material 3 having H1T=WOB/WOTXH1B in the thickness W1B on the broad side and the thickness H1T on the narrow side is obtained. The rolled material is rotated 90 deg., and is subjected to ordinary rolling with horizontal rolls from the direction at a right angle to the above-described screw down direction, whereby the thickness 1B or suitable thickness below the same is obtained. Thus the H1T and H1B are made equal and the W0T and W0B equal, and a rolled material 4 of a rectangular shape is obtained.
