Abstract. The paper presents a new type of rolling with the continuous feeding of billet in the zone of deformation, i.e. a combination of rolling and pressing-out. The authors consider getting of thickened flanges out of hollow billets, which can be carried out as with the help of the tapered roller and so with the help of cylindrical rolls. The results of the process modeling in the complex Deform 3D are given. The proposed technology is especially effective for the production of flanges out of tubing, for the connection of which they are intended.
