Abstract
The present invention relates to a wire rod rolling line in which a finishing mill group rear stage is composed of a combination of a plurality of 4-roll mills. An object of the present invention is to provide a wire rod rolling line having a very high operating ratio capable of expanding a size free rolling range and at the same time capable of arranging pass schedules in which the pass schedule of an upstream pass is simplified in order to shorten a line stop time for adjusting mills. To achieve the object, the wire rod rolling line of the present invention is arranged such that three mills from the end of the finishing mill group are 4-roll mills, these three mills are installed in series with the reducing directions thereof dislocated by 45°, the two mills from the end are driven by a common motor and the third 4-roll mill from the end is separately driven.
