FIELD: technological processes, metal processing.
SUBSTANCE: invention concerns rolling mill equipment, particularly to cold-roll profiles and profiled pipe production aggregates. Aggregate includes graded profile rolling mill with two-high shaping stands, drive and retracting guide rail, as well as multipurpose stands and drive. Three four-high stands with individual drive and adjustable height and width calibration without roller replacement are used as multipurpose stands and feature feeding guiding rail, device feeding pipes onto this guiding rail, as well as retracting guiding rail. Retracting guiding rail of graded profile rolling mill and feeding guiding rail of multipurpose stands have common chain drive positioned between them.
EFFECT: expanded technological capacity, reduced production cost.
