|発明の名称||WARM CONTROLLED ROLLING APPARATUS AND WARM/COLD CONTINUOUS CONTROLLED ROLLING APPARATUS|
PROBLEM TO BE SOLVED: To provide a rolling apparatus with which thin metallic wire of heavy unit weight of the degree which is not obtained previously with a compact apparatus by performing the controlled rolling in the range of warm-rolling temperature by continuously heating a high-strength metallic wire or a thin wire excellent in working properties of cold heading property or the like by having a level excellent in the balance between the strength and the ductility by ultra-fine crystalline grain structure without applying special heat treatment to a manufactured metallic wire or the thin wire while suppressing the cost of energy.
SOLUTION: A first rolling mill provided with a pair of two bar-mill rolls which are perpendicular to the direction of a rolling line of a metallic material to be rolled and the shaft centers of which are parallel and a second rolling mill provided with a pair of two bar-mill rolls which are adjacent to the downstream side of the rolling line of the first rolling mill, perpendicular to the reduction direction of the metallic material to be rolled and the shaft centers of which are parallel are arranged at a close distance.
