FIELD: metallurgy.
SUBSTANCE: method includes heating of metal, pre-forming of consisting of connected to each other by jumper parts of profile and separation of received profile for parts by destruction of connecting jumper by means of nonpowered division device. Optimal conditions for providing of directional stability of strip at its division are provided ensured by that at distraction of jumper axle base between rolls forming coupled profile, and rollers of nonpowered division device should not exceed value regulated by mathematical dependence.
EFFECT: reduction of discard and power inputs connected to division of rolling metal, reduction of wear of equipment at manufacturing of symmetrical and non-symmetrical profiles.
