STEEL STRIP STRAIGHTENING METHOD Russian patent published in 2005 - IPC

Abstract RU 2255825 C1

FIELD: metallurgy, namely finishing rolled strips, possibly straightening steel strips with lengthwise alternating corrugations.

SUBSTANCE: method comprises steps of multiple elastic-plastic sign-variable lengthwise bending of strip and simultaneous crosswise bending of it due to increased bending of edge ( along strip width) portions in comparison with mean portion of strip; providing bending value of edge portions more than that bending value of its mean portion at first bending operation and at each next bending operation providing bending value of edge portions less than that of previous bending operation; successively reducing values of lengthwise bending along straightening process direction from predetermined value to zero.

EFFECT: lowered wear of rollers, enhanced quality of straightening.
