Wire rods having various sectional shape are generally used in various applications. In a 2-roll shape rolling process, step-by-step rolling operation is executed repeatedly and the rollers must be changed whenever the sectional shape of wire rod is changed. The frequent changes of the rollers and discontinuous repeated operations are cause various shortcomings such as increase of manufacturing cost and reduction in precision. We had developed a high precision automatic wire rod manufacturing system to reduce these shortcomings in the previous study. In this study, we evaluated the field application performance of the developed system in terms of straightness, thickness deviation, surface precision, tensile and hardness of the wire rod in order to verify the feasibility of the system.
