FIELD: process engineering. ^ SUBSTANCE: invention relates to roll mill stand and roll mil for production of multiface profiles. Proposed stand comprises at least three rolls fitted their axles arranged in one plane. Note here that roll axles are arranged at over 0 and less than 180 degrees at each other. Note also that each roll has round work surface and, together, the rolls form a gage. Work surface of at least one roll features invariable shape that has in its cross section in axial plane at least one plain section parallel to axis and one inclined section running at over 0 at less than180 to said plain section adjoining to the latter and directed outward from plain section relative to axle. Roll mill has at least two roll stands. Note here that aforesaid plain section of the first stand features width different from that plain section of the second stand roll. ^ EFFECT: reduced deviation from preset hexagonal shape. ^ 18 cl, 8 dwg |
