The effect of the edging on the plate profile has been studied by a 1/10 model of plasticine. The plate profile was improved by the adoption of combination of longitudinal and cross directional edging. At Plate Mill in Nagoya Works, the optimum system of longitudinal and cross directional edging was accomplished by studying experimentally the change of plate profile through edging and flat rolling. The proper rectangular plate profile has been made by making, firstly, the plate profile concave type by cross directional edging before broadside rolling and secondly by edging in longitudinal direction after the broadside rolling. The aimed value of rolling width was decided by considering the width change at finishing stage. The yield of plate mill has been improved by 3% using this system.
