Abstract

PURPOSE: For economical and efficient special shape rolled plate production, trapezoid slab with constant wall thickness and varied width in rolling direction is first produced, then such slab is turned 90° degrees to the rolling direction, and rolled in finishing size.
CONSTITUTION: A trapezoid slab with a constant thickness t0 and varied width from 2a0 to 2b0 in the longitudinal direction is produced by changing continuously or stepwisely the opening of either edger roller or horizontal roller, the former for slab rolling or rough rolling of slab from ingot, the latter for elongated raw material. The slab rolling direction R0 is the same as its longitudinal direction Y axis. Then, the slab is turned 90° degrees so that finish rolling direction R1 will correspond to X axis. Thus, the process provides an easy and economical means for trapezoid plate production permitting the use of existing installation.
