The problem of band rolling from the billets having wedging cross section has arisen during operation of the 5-stand rolling mill 630 of Magnitogorsk Metallurgical Works. As a result, transversal gauge interference is forming. Therefore, increase of metal cross section during deformation is considered as one of the possible ways of wedging lowering. This paper presents analysis of possible adjusting effects on metal widening based on mathematical simulation using finite elements method. Influence of friction conditions, level of tensions between rolling stands and reduction value has been examined. For example, lowering of friction ratio from 0.1 to 0.03 increases metal widening by 6.5–10 % and rise of singular reduction in the 1st and 2nd rolling stands from 10 to 20 % allows to elevate metal widening by 125–150 %. Rational deformation procedures of cold rolling for band with width 285–465 mm have been developed on the base of obtained data; these procedures allow to increase maximally metal widening during deformation process.
