摘要： A method for direct patenting of a hot-rolled wire rod comprises the steps of: transporting a hot-rolled wire rod on a conveyer in a state that said wire rod is in a form of continuous series of loops; blasting mist to the surface of said wire rod at least from above and blasting air to the back side of the wire rod from below to cool the wire rod at a rate of 12 DEG C. to 50 DEG C./sec. down to 550 DEG C. to 400 DEG C. during the transportation, the mist provides 200 to 2400 l/min. water and has an air to water ratio of 200 Nm3/m3 or less; and reheating the cooled wire rod at a rate of 3 DEG C./sec. or less, or cooling the cooled wire rod slowly at a rate of 2 DEG C./sec. or less during the transportation. In addition, another method for direct patenting of a hot-rolled wire rod comprises the steps of: transporting a hot-rolled wire rod on a conveyer in a state that the wire rod is in a form of continuous series of loops; cooling, as a first cooling step, the wire rod at a rate of 12 DEG to 40 DEG C./sec. down to 600 DEG C. to 450 DEG C. during the transportation by means of blasting a cooling medium to the wire rod for 5 secs. to 30 secs.; and cooling, as a second cooling step, the cooled wire rod st a rate of 2 DEG C. to 15 DEG C./sec.down to 550 DEG C. to 400 DEG C. during the transportation by means of blasting a cooling medium to the wire rod cooled in the first cooling step for 5 secs. to 30 secs.

摘要： A method for transporting a hot-rolled wire rod (13) comprises changing directions of movements of the wire rod to the left and to the right relative to the center line of a conveyer (10) at an interval of d/3 to 2d of a diameter of a ring of the wire rod and shifting the center of the ring of the wire rod from the center line of the conveyer by a length of 2d/100 to 30d/100 at its maximum. An apparatus for transporting hot-rolled wire rod comprises a conveyer (10) for transporting a hot-rolled wire rod (13) and guide device (14) alternately arranged in an upper portion of the side of the conveyer to change the directions of movements of the wire rod to the left and to the right relative to the center line of the conveyer. A further apparatus for transporting hot-rolled wire rod comprises side walls arranged in zigzags facing each other on the both sides of the conveyer to have the wire rod move in zigzags with the center line of the conveyer as the center and guide devices arranged on the side walls arranged toward the center line of the conveyer.
