Abstract

PURPOSE:To eliminate the melting cut and restraightening stages and to efficiently obtain unequal angle steels by rolling a stock having a nearly Z-shaped section by rough rolling, bringing the stock to be gradually thinner by the succeeding finishing rolling, and introducing the stock to a pass in which the web is cut and correctly formed during rolling. CONSTITUTION:A stock having a nearly Z-shaped section is rolled by rough rolling and is gradually thinned by the succeeding finishing rolling. Then, the stock is introduced to a pass in which the web is cut and correctly formed. Thus, extra stages such as melting cut and restraightening are eliminated, unequal angle steels separated into two pieces by rolling are rolled with high productivity without over or short filling of a material.
