Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To control the bias of web of a wide-flange steel by cooling a flange lower part on the bottom part or the top part of the wide flange steel and controlling the dimension of the flange width in a process after intermediate rolling and before finishing rolling. SOLUTION: This cooling device is composed of three cooling zones, and each zone is arranged with many cooling jetting nozzles in the rolling direction of this H-shape steel. When the bias is made larger, cooling is increased, when the bias is made smaller, cooling is reduced. The power of cooling depends on its jetting time of a cooling water, the H-shape steel is cooled during movement of the steel, and the cooling time is controlled by on/off of the cooling water per each zone unit. The position to jet the cooling water is aimed at the flange lower part of the H-shape steel. In the flange lower part of the next process finishing by cooling the lower part, the longitudinal elongation of the steel is restricted, the steel is elongated to the width direction of the flange and this is acted to the direction of solving the web bias.
