PROBLEM TO BE SOLVED: To provide the manufacture of the T-shape steel with few bending and deformation and excellent in stability of manufacturing. SOLUTION: In this manufacture of the T-shape steel, finish rolling is performed to H-shape steel 2 or I-shape steel by a finishing universal mill group 1. Simultaneously with the finish rolling, the T-shape steels 4a, 4b are obtained by cutting a web 22 in the longitudinal direction by a hot saw 3. Just after that, the T-shape steels are transferred on a roller table 5 while restricting a flange 21 by restraint rolls 6, and the rear surface of the flange 21 is cooled by a spray nozzle 7. |
