STRIP HOT ROLLING Russian patent published in 2013 - IPC B21B1/26

Abstract RU 2492005 C1

FIELD: process engineering.

SUBSTANCE: proposed method comprises strip hot rolling at wide-strip finishing mill stands equipped with device for bending working rolls in vertical plane. Redistribution of unit stress at inlet and outlet cross-sections of deformation zone that decreases difference in finished strips thickness is brought about by measuring the departure of strip width behind the last finishing mill stand ΔB=B_act-B_setfrom preset magnitude and affecting working roll bending forces at said stands in compliance with mathematical expression allowing for empirically defined "bending force-width" ratio factor.

EFFECT: stabilised width of hot-rolled strips.
