FIELD: manufacturing of metal beams.
SUBSTANCE: invention relates to a method for manufacturing metal beams with a hat profile. Hot rolling of a solid billet is carried out in a rolling mill line containing at least two rolling stands. From the initial section of a solid billet using at least two shaped gauges during one rolling process in said at least two rolling stands at a hot rolling temperature, an output section with a hat profile is obtained through a single uneven calibration, having angular deviations of the flanges of the hat profile from 0.1 degree to 15 degrees relative to the horizontal. These angular deviations are eliminated through a bending process using a straightening machine or an additional universal rolling stand.
EFFECT: technological capabilities are expanded and the method of manufacturing metal beams with a hat profile is simplified.
