Claims (1)

Способ производства бесшовных горячекатаных труб, включающий прокатку гильзы-трубы в двух последовательно расположенных станах продольной прокатки (тандем) с вытяжкой в каждом стане в валках с многогранными калибрами на коротких неподвижных конусно-цилиндрических оправках, отличающийся тем, что прокатку гильзы-трубы производят в валках, высоты калибров которых равны для обоих станов, с вытяжкой на первом стане μ1=1,2-1,9 (где μ1 - коэффициент вытяжки на первом стане) и вытяжкой на втором стане μ2=1,0-1,07 (где μ2 - коэффициент вытяжки на втором стане) на оправках, наружные диаметры которых или равны для обоих станов (d2=d1), или наружный диаметр оправки второго стана на 1 мм больше наружного диаметра оправки первого стана (d2=d1+1 мм) [где d2 - диаметр оправки второго стана, мм; d1 - диаметр оправки первого стана, мм).A method for the production of seamless hot-rolled pipes, including the rolling of a sleeve-tube in two successive longitudinal rolling mills (tandem) with an extract in each mill in rolls with multifaceted calibers on short stationary cone-cylindrical mandrels, characterized in that the rolling of the sleeve-tube is carried out in rolls , the caliber heights of which are equal for both mills, with a hood on the first mill μ 1 = 1.2-1.9 (where μ 1 is the hood coefficient on the first mill) and a hood on the second mill μ 2 = 1.0-1.07 (where μ 2 - at the second reduction ratio tane) on the mandrels, the outer diameters of which are equal to or for both mills (d 2 = d 1) or external diameter of the second mandrel mill 1 mm larger than the outer diameter of the first mandrel mill (d 2 = d 1 +1 mm) [where d 2 - the diameter of the mandrel of the second mill, mm; d 1 - the diameter of the mandrel of the first mill, mm).
