Abstract:
To efficiently and stably produce an H-shaped steel product with a flange width larger than a conventional flange width and prevent a shape defect from occurring in shaping using a flat shaping caliber at a rough rolling step. A rolling mill that performs the rough rolling step is engraved with a plurality of calibers configured to shape a material to be rolled, the number of the plurality of calibers being five or more; shaping in one or a plurality of passes is performed on the material to be rolled in the plurality of calibers; a first caliber and a second caliber of the plurality of calibers are formed with projections configured to create splits vertically with respect to a width direction of the material to be rolled; in the second caliber and subsequent calibers of the plurality of calibers, reduction is performed in a state where end surfaces of the material to be rolled are in contact with peripheral surfaces of the calibers in shaping in at least one pass or more; in a third caliber and subsequent calibers excluding a final caliber of the plurality of calibers, a step of sequentially bending divided parts formed by the splits is performed; and the final caliber of the plurality of calibers is a flat shaping caliber, and rolling and shaping in the flat shaping caliber is performed under a rolling condition that a pulldown rate is 1.0 or less.

Claim (Index 2):
The method of producing the H-shaped steel according to  claim 1 , wherein\n in production of H-shaped steel having dimensions of 1500 mm\u00d7600 mm, the rolling and shaping in the flat shaping caliber is performed under a rolling condition that a web thickness of the material to be rolled after rolling and shaping becomes 160 mm or more.
