где σто - предел текучести прокатываемого металла в исходном состоянии, кгс/мм2; 0,7-1,2 - коэффициенты, большее значение которого выбирается при относительных обжатиях ε=0,1, меньшее - при ε=0,4; S - минимальная площадь поперечного сечения изделия, мм. К противоположному концу прикладывают усилие протягивания, под действием которого протягивают между парой неприводных валков, которым сообщают радиальное перемещение, величину которого жестко связывают с величиной продольного перемещения и определяют для каждого рабочего хода программой обработки. По оканчании рабочего хода возвращают в исходное положение и одновременно поворачивают вокруг продольной оси.The invention is intended for the manufacture of non-rigid articles of face section in the form of a wedge in the longitudinal direction. The goal is to expand technological capabilities. To the end of the fixed billet, located on the side opposite to the place of indentation of the rolls, for the entire time of rolling an axial anti-tension force P n is applied, the value of which is determined from the dependence
where σ then - the yield strength of the rolled metal in the initial state, kgf / mm 2 ; 0.7-1.2 - coefficients, a larger value of which is selected for relative reductions ε = 0.1, less - for ε = 0.4; S - the minimum cross-sectional area of the product, mm. A pulling force is applied to the opposite end, under the action of which it is pulled between a pair of non-driven rolls, which are reported to have a radial movement, the value of which is rigidly associated with the value of the longitudinal movement and determined for each working stroke by the treatment program. Upon completion of the working stroke return to its original position and at the same time rotate around the longitudinal axis.
