PURPOSE:To prevent the over-cooling of the front and rear parts of a coiled wire rod by reducing the rate of transfer of the wire rod on a conveyor when the front and rear parts are transferred and by making the density of overlap of rings in each of the front and rear parts higher than that in the middle part. CONSTITUTION:A coiled wire rod rolled with a hot rolling mill is unfolded and transferred on a conveyor, and controlled cooling is carried out during transfer to obtain prescribed quality and characteristics. At this time, the rate of transfer of the coiled wire rod 12A on the conveyor is reduced when the front part 12B and the rear part are transferred. At the same time, the density of overlap of rings in each of the front part 12B and the rear part is made higher than that in the middle part 12C. |
