PURPOSE:To cool a wire rod uniformly in developing a hot rolled wire rod to annular shape on a roll conveyor and cooling by air blasting from below the conveyor by making the diameter of rolls at both ends of the roll conveyor smaller than the diameter of the central part. CONSTITUTION:In developing a hot rolled wire rod 3 to annular shape by the roll conveyor and cooling by air blasting from below the conveyor, the diameter of both ends 1b, 1b' of the body of the conveyor roll 1 is made as small as 20-90% of the diameter of central part 1a of the body. The length (l) of the central part 1a of the body is made 70-90% of the diameter D of the annular wire rod 3. In this way, the superposed wire rod 3 at the end of the roll 1 is cooled similarly to the central part, and the cooling of the wire rod can be made uniform. |
