Abstract

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.

Description

technical field

[0001] The present invention relates to a wire rod cooling device and a wire rod cooling method for adjusting and cooling the wire rod conveyed by a conveyor after coiling the wire rod formed by hot rolling of a billet into a non-concentric ring shape.

[0002] This application claims priority based on Japanese Patent Application No. 2013-224279 for which it applied to Japan on October 29, 2013, and uses the content here. Background technique

[0003] The wire rod formed by the hot rolling of the billet is cooled to about 800° C. to 900° C. by a water cooling method, and then coiled into a non-concentric ring shape by a laying head (wire rod coiler). The coiled non-concentric annular wire (hereinafter also simply referred to as "annular wire") is transported by a conveyor provided on the exit side of the wire laying machine, and is further cooled by a cooling device while being transported. Water cooling and cooling after coiling are called conditioning cool...
