The invention relates to sheet-rolling production and can be used on the wide-strip rolling mills. In a set of rolls of two-high mill stand a body of each of the rolls contains the convex middle part and the symmetrical cylindrical sections located along the edges of body. The width of convex section of body of the first roll makes 0.25… 0.5 of the length of body, while the width of convex section of body of the other roll males 0.5… 0.75 of the width of convex section of the first roll. Technical result consists in formation along both sides of the billet of wide rigid lateral areas, which contributes to reduction of widening the billet in its finite segments and metal consumption at their cutting, increase of the stability of the process of rolling and efficiency of formation of shaped ends at the ends of billet.
