FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Rolling mill for rolling strip 4 has several main stands 1, 1' and reeler 2 arranged there behind. Said main stands incorporates working rolls 5, 5' and, at least, bearing rolls 6, 6'. Rolling mill control device 3 receives data on strip 4 to define, at least, one reduction A other than zero of strip 4 of all passes at rolling mill. Control device 3 uses entered data to define reduction of single pass for main stands 1, L. Said control device controls over stands 1, 1' and reeler 2 to make strip 4 be rolled in main stands in compliance with definite single-pass reductions and, then reeled, by reeler 2. Single-pass reduction of the main stand 1' arranged immediately ahead of reeler 2 equals zero while outlet side tension in strip 4 is smaller than that and inlet side. Strip 4 passes through said stand L with no deformation on, at least, one side.
EFFECT: higher quality of strip.
