PROBLEM TO BE SOLVED: To provide a trough device in a wire hot rolling, in particular excellent in an exchange cost of equipment at the time of trough abrasion and in a working efficiency of exchange at the time of alteration of a wire diameter in connection with a water-cooling trough and forced-cooling trough in a wire hot rolling equipment. SOLUTION: In a wire hot rolling equipment, a water-cooling trough device including a normally vertical and inversely vertical trough, capable of vertically dividing into two for water-cooling a wire during a hot rolling and capable of exchanging only nozzle part, is arranged. The water-cooling trough device is capable of exchanging only contact part in accordance with the alteration of the wire diameter and the abrasion at the contact part. And a forced-cooling trough device uniformalizing a temperature group which is generated on the surface of the wire, capable of vertically dividing into two, is arranged. The forced-cooling trough device is capable of exchanging only contact part in accordance with the alteration of the wire and the abrasion at the contact part.
