WIRE ROD COOLING DEVICE AND WIRE ROD COOLING METHOD

摘要

A wire rod cooling device for cooling a wire rod wound in a ring shape by a wire rod winder while conveying the wire rod on a conveyor is provided with: a plurality of jet nozzles which are disposed along the width direction of the conveyor and each jet a refrigerant toward the wire rod; an image capturing unit which is provided on the conveyance line upstream side of a jet nozzle row composed of the plurality of jet nozzles and captures an image of the wire rod that is being conveyed; and a control unit which extracts density information and temperature information relating to the wire rod from the captured image. On the basis of the density information and temperature information relating to the wire rod, the control unit controls the flow rate of the refrigerant to be jetted from each of the jet nozzles with respect to each of the jet nozzles in accordance with a timing when a specific portion corresponding to the information arrives at the jet nozzle.
