FIELD: transportation.
SUBSTANCE: technological calibration tool includes series of several forming pinch passes and final calibration and trimming passes for finished product. Roll passes for final calibration are compound to enable relative rotation of working roll surfaces forming profile areas and removed from roll rotation axis at different distance. Just one element out of roll components is guiding, and guided elements of compound rolls feature bearings.
EFFECT: reduced power consumption of mill; improved article quality and precision and enhanced life time of tool.
