METHOD OF OPERATING SHEET-ROLLING MILL ROLLS Russian patent published in 2013 - IPC B21B28/02

Abstract RU 2492948 C1

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy and can be used in rolling at sheet-rolling mills and planishing mills with working rolls with different in body diameter and individual and common drives. Proposed method comprises grinding of rolls and grooving of their bodies. Note here that roll surface denting of smaller-diameter body to surface roughness exceeding that of larger-diameter roll while smaller-diameter roll roughness is defined by the formula $R_{а} (s) = k \cdot \frac{D_{L}}{D_{S}} \cdot R_{а} (l) :$ where R_a(s), R_a(l) is smaller- and larger-diameter roll body roughness, mcm ; D_S, D_L are roll body smaller- and larger-diameters, mm; k=2÷4 is coefficient of proportionality.

EFFECT: ruled out additional grinding, lower costs and labor input.
