ROLLER GUIDE Russian patent published in 2009 - IPC B21B39/16 

FIELD: metallurgy.

SUBSTANCE: invention refers to rolling mill industry, particularly to designs of roller guides and can be implemented in section and wire mills. The roller guide for entry of rounded band into the section mill stand contains pair of non-driven rollers, arranged opposite to each other and secured so, that distance between axes can be altered. Circular U-shaped cuts are made on cylinder surfaces of the rollers. Each of sides of the circular cut is made curvilinear with radius of curvature 0.7-1.1 from thickness of the band and coupled with rectilinear section of the cylinder generatrix along the circumference arc. Additionally, radius of coupling arc of circumference is 0.3-0.5 from radius of curvature of side of the circular cut.

EFFECT: upgraded quality of section band and eliminating its jamming in mill.
