Claims

[Scope of utility model registration request]

In a horizontal roll of a universal mill for a section steel, in which the side inclination angle of the roll body that contacts the inner surface of the flange of the material to be rolled is formed within 10 degrees, at least the side surface of the roll including the part corresponding to the tip of the flange of the section steel is pre-rolled. A horizontal roll for a universal mill for shaped steel, characterized by forming an annular welded layer that is abrasive.
