Definitions
- the invention relates to a working method for XH rolling of parallel-flanged steel profiles (beams) with H-profile in tandem operation in a compact rolling group, which consists of a first universal stand, a downstream stand and a subsequent, second universal stand, the rolling of the Scaffolds inclined, or have rolling surfaces running vertically to the axes of the rolls.
- Either pre-rolled continuous casting material is used as the raw material for the tapping in this compact rolling group, the preliminary rolling being carried out on a conventional breakdown stand or in a vertical-horizontal reversing rolling group or a horizontal-universal or vertical-horizontal-universal reversing rolling group.
- the object of the invention is to reduce the wear of the horizontal rollers, to coordinate them for both stands and to keep them as identical as possible.
- This object is achieved in that when using vertical rollers with rolling surfaces inclined between 0 degrees and 10 degrees away from one another in the first universal stand and vertical rollers with cylindrical rolling surfaces in the second universal stand, the side surfaces of the horizontal rollers, which with the roller surfaces of the vertical rollers, Form the caliber, have inclinations of 0.0 degrees to 0.5 degrees and to bring about a reduction in the rolling stock in the second universal stand which is 0-100% of the decrease achieved in the first universal stand.
- the outer bale length of the horizontal rolls of the second universal stand can advantageously correspond to the inside dimensions of the H-beam to be rolled.
- the application of the working method according to the invention makes it possible to simultaneously turn the rollers of both universal stands and thus to determine the cost-effective point in time and, through this coordination, also to reduce the material waste and thus the total production costs.
