METHOD FOR PREVENTING SLIPPING OF ROLLERS OF QUARTO SHEET ROLLING MILL CAGE Russian patent published in 2023 - IPC B21B1/22 B21B37/16 B21B38/04

Abstract RU 2808119 C1

FIELD: strip rolling.

SUBSTANCE: invention is related to a method for rolling strips in the stand of a quarto sheet rolling mill. The conditions for slipping of the quarto stand rolls are determined by comparing the strip thickness in the neutral section with the minimum strip thickness in the deformation zone. Prevention of slipping of the work rolls relative to the strip is ensured in the case when the thickness of the strip in the neutral section is greater than the minimum thickness of the strip in the deformation zone.

EFFECT: negative self-oscillatory effects during cold rolling are eliminated.
