FIELD: mill products.
SUBSTANCE: invention relates to the rolling of an angular asymmetric profile of the check rail angle type. The profile is rolled in 7 passes in a crimping 2-high mill with edging after 2, 4, 5, 6 passes in a rectangular caliber. Then it is turned and rolling is continued in the 3-high mill I “trio” in 3 passes of rolls in shaped calibers. After that, rolling is carried out in the pre-cleaning mill II “trio” in 3 passes of rolls in sectional grooves. The final design of the profile is made in the finishing mill III “duo” in 1 roll pass in a sectional groove.
EFFECT: as a result, metal consumption decreases and productivity increases.
