FIELD: process engineering. ^ SUBSTANCE: invention relates to production of long cylindrical articles, in particular, to production of calibrated steel and wire. Proposed method comprises plastic deformation by cyclic alternating-sign bending. Deformation is performed with decreasing bending strain degree from initial value to bending strain at final stage. Initial values makes, at least, 2%. At final stage, strain equals billet metal yield strength. Proposed device comprises sections for rollers, each being made up of top and bottom angles articulated by their input and output ends. Inner surface of flange of each angle accommodates vertical and horizontal rollers and mechanisms of angle input and output ends rolling. Vertical and horizontal rollers of top angle are arranged alternating with vertical and horizontal rollers of bottom angle. Said rollers make working channel for billet drawing. ^ EFFECT: reduced strength characteristics of billet metal. ^ 9 cl, 9 dwg |
