Abstract
PURPOSE:To carry out uniform cooling and obtain a steel wire rod with superior characteristics by using warm water as a cooling medium in patenting and leaving a space between the bottom plate of a coiler and the bottom of a treatment vessel so that the water is smoothly circulated. CONSTITUTION:A steel wire rod heated to the austenitizing temp. is patented to be converted into of fine pearlite structure. At this time, pores of a porosity above 20% are made in bottom plate 6 of laying coiler 4 for coiling the rod, and plate 6 is set apart from bottom 7 of the treatment vessel. Warm water 5 for cooling is stirred and circulated by use of impeller 8 or by blowing steam to make the temp. of the water in the vessel uniform. Thus, all of the wire rod rings are uniformly cooled in the vessel. Using the sensible heat of hot rolling, the rod is directly patented to be given superior tensile strength.
