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 wirerod. 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. In this study, in order to apply a highly precise 4 roll rolling mill developed in previous studies on the shape rolling manufacturing process, the raw wire feeding equipment, 2 roll rolling mill, turks Head rolling mill, largeheat treatment equipment, a steam cleaning equipment, a large winding equipment, cooling equipment, a tension adjustment equipment, designed and manufactured to the main control system. In addition, the problems corrected throughout these various equipments for manufacturing high-precision automatic rolling mill system developed by assembling more than six months and was conducted between complementary and testing process.
