FIELD: plastic metal working. SUBSTANCE: method comprises steps of determining admissible values of shear deformation by twisting and tension according to analytical dependences received at experimental testing of plastic properties of steels and alloys at twisting; setting values of above mentioned parameters by changing feed angle of rolls of screw rolling stand; determining said angle according to analytical relations. EFFECT: stable process of out- of-roll deformation by twisting between adjacent stands for screw and lengthwise rolling, elimination of rupture of rolled piece and prevention of distortion of its geometry size.
