Wire rods having various sectional shape are generally used directly in various applications. In the shape rolling, a couple of grooved rollers are used and the groove match the sectional shape of the wire rod. In this 2 roll system, a couple of rollers must be changed whenever the sectional shape of the wire rod is changed, and the frequent changes of roller cause rise of manufacturing cost. We developed a 4 roll wire rolling mill that reduce the disadvantage of 2 roll rolling, at the same time improving quality of the wire rods and reducing production costs. The present work is focused on the development of a high precision 4 roll wire rolling mill for the wire rods that have various rectangle sectional shape.
