STRIP HOT ROLLING

摘要

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 ?B=B-Bfrom 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.1 dwg, 1 ex
