FIELD: technological processes.
SUBSTANCE: invention relates to metal forming and heat treatment, particularly, to production of articles from hard-to-strain, high-strength metals and alloys, including titanium and its alloys, nitinol. In method of multiple drawing of item with electric contact heating, which involves drawing of workpiece through serially arranged deforming devices with simultaneous passing through billet of electric current of specified parameters, deforming devices are rollers, which are electrically insulated from each other, supply of electric current to the workpiece is carried out through a current-feeding device located before the first in the direction of drawing roller cage, and through the last along the drawing process roller cage, note here that resistive shunts and / or additional current sources are connected between roller cages in parallel billet.
EFFECT: higher quality of articles due to reduced surface defects.
