FIELD: technological processes.
SUBSTANCE: rolling mill comprises two sets of working rollers - upper and lower, barrels of which are arranged in the form of truncated cones, besides rollers are turned relative to each other by 180° so that their axes preserve parallelism. Value of rollers taper is set in range that provides direction of transverse component of total speed of metal sliding in deformation zone from the middle of strip to its edges with preservation of dragging and advancing zones. Range of rollers taper value is regulated by mathematical dependence.
EFFECT: lower level of residual stress in strip.
