ABSTRACT:
A method for the rapid, direct cooling of a hot-rolled wire rod comprising the steps: transporting a hot-rolled and coiled wire rod on a conveyor, the wire rod being in a form of continuous series of loops; and blasting an air-water mist to the wire rod and simultaneously blasting air to the back side of the wire rod from below to cool the wire rod at a rate of 10.degree. to 100.degree. C./sec, while transporting the wire rod on the conveyor, the air-water mist providing 0.5 to 10 m.sup.3 /minute water and having an air to water ratio of 200 Nm.sup.3 /m.sup.3 or less. Furthermore, a method for the rapid, direct cooling of a hot-rolled wire rod comprising the steps of: transporting a hot-rolled and coiled wire rod on a conveyor the wire rod being in a form of continuous series of loops, advancing the wire rod in a zigzag configuration during the transportation and blasting an air-water mist to the wire rod and simultaneously blasting air to the back side of the wire rod from below to cool the wire rod at a rate of 10.degree. to 100.degree. C./sec, while transporting the wire on the conveyor, the air-water mist providing 0.5 to 10 m.sup.3 /minute water and having an air to water ratio of 200 Nm.sup.3 /m.sup.3 or less.
