Rolling apparatus and method for producing the steel ribbed h

The present invention discloses an apparatus and a method of producing a rolling ribbed H-beam. Rolling apparatus comprising means for rolling a rolled H-section steel ribbed body for rolling the upper and lower rib and the rib of the ribs on the ribbed rolling H-shaped steel body; the rib having an upper horizontal roll mill and the center axis of the horizontal rolls, the central axis of the upper horizontal roll and the lower horizontal rolls are parallel and vertically symmetrical with respect to the web. The rolling method of billet comprising rough rolling BD blooming process; by the blank BD after slabbing process universal rough rolling at a rolling finish rolling the rolled H-shaped steel body ribbed process, a rolling process after the finishing universal rolling, the rolling mill using the ribs on the ribbed H-shaped steel body lower rib and upper ribs. The present invention, by the above aspect of saving the production cycle and the manufacturing cost of steel production company, while avoiding weld cracks caused by the welding ribs to improve the stability and rigidity of the H-beam ribbed.
