FIELD: metallurgy.
SUBSTANCE: method includes rolling in draft and final four-roll universal calibers with horizontal and vertical rolls, the latter of which are made with profile creeks and coils on the side of the profile head, and in the pre-final two-roll caliber of the open type. Rolling is carried out in a final four-roll caliber with a connector made on the side of the rail head between the rolls of the vertical roll and the ends of the horizontal rolls in the areas of the conjugation surfaces with the side surfaces of the rail head. The radius of the mentioned conjugations in the pre-final two-roll caliber is regulated by the mathematical dependence.
EFFECT: increasing the profile accuracy and stabilising the rolling conditions.
