Abstract (en)
[origin: WO9517269A1] This invention relates to a method of manufacturing H-steel used for building. The method according to the present invention is used for the intermediate rolling of H-steel in a mill unit UT in which a universal roughing mill UR and a universal edger mill UE are arranged close to each other, characterized by pressing down free end portions of a flange by a horizontal roll of the UE with the width of the horizontal roll set smaller than that of a corresponding roll of the UR and with an outer surface of the flange held by a vertical roll of the UE, and pressing down the flange in the direction of the thickness thereof with the horizontal roll of the UE set width-variable and with a bore mold formed by the horizontal roll and vertical roll. This enables the buckling of the flange during the pressing of the flange in the widthwise direction thereof by the UE will to be prevented, and H-steel having a dimensional precision/comparable to that of welded H-steel to be manufactured by hot rolling.
