PROBLEM TO BE SOLVED: To obtain a T-steel whose bends and deformation are minimized and which is excellent in the stability of manufacture by cooling the outside of flange while transporting T-steels on a roller table overlapping the webs vertically after obtaining two T-steels by executing finish rolling of a wide- flange shape steel or an I-steel with a universal mill and simultaneously cutting its web in the longitudinal direction. SOLUTION: After the wide flange shape is cut into T-steels 4a, 4b with a hot saw which is provided on the downstream side of the universal mill group, immediately those T-steels are transported on the roller table 5 while making the position of the H-shaped hold by supporting them in a state where the webs 22 are vertically overlapped with a jig 6 on the roller table 5. During transporting, cooling water is jetted from spray nozzles 7 on the outsides of the flanges 21. In such a case, by adjustion the flow rate of each spray nozzle 7 and intermittently thinning, flange cooling is controlled. |
