Claims (4)

1. Калибровка валков для редукционного трубопрокатного стана, содержащая комплекты валков, каждый из которых состоит из трех валков при работе без применения оправки, в которой вогнутые контуры калибра валков имеют выпуклости с обеих боковых сторон каждого валка, отличающаяся тем, что размер (а) выпуклости (5) боковых сторон (4) калибра по меньшей мере у нескольких комплектов валков, следующих друг за другом в направлении прокатки, увеличивается на постоянные или одинаковые в процентном отношении величины.1. Calibration of the rolls for the reduction tube mill, containing sets of rolls, each of which consists of three rolls when working without the use of a mandrel, in which the concave contours of the caliber of the rolls have bulges on both sides of each roll, characterized in that the size (a) of the bulge (5) the sides of the (4) gauge of at least several sets of rolls following each other in the rolling direction increases by constant or the same percentage. 2. Калибровка валков по п.1, отличающаяся тем, что увеличение выпуклости (5) соответствует 1 - 5% от толщины стенки труб, подлежащих прокатке в калибре. 2. Calibration of the rolls according to claim 1, characterized in that the increase in convexity (5) corresponds to 1 - 5% of the wall thickness of the pipes to be rolled in caliber. 3. Калибровка валков по пп.1 и 2, отличающаяся тем, что верхняя точка (6) выпуклостей (5) на каждой боковой стороне (4) калибра, начиная от основания (3) калибра, и относительно средней точки (7) калибра комплекта валков расположена со смещением 30 - 35o в направлении выступа (8) валка.3. Calibration of the rolls according to claims 1 and 2, characterized in that the upper point (6) of the bulges (5) on each side (4) of the caliber, starting from the base (3) of the caliber, and relative to the midpoint (7) of the kit gauge rolls is located with an offset of 30 - 35 o in the direction of the protrusion (8) of the roll. 4. Калибровка валков по пп.1 - 3, отличающаяся тем, что имеется сопряженное количество, равное максимум 12 клетям, из рабочих клетей (от i до i + n), следующих за обжимными (черновыми) клетями, с выпуклостями (5) на боковых сторонах (4) калибра. 4. Calibration of the rolls according to claims 1 to 3, characterized in that there is a conjugate amount equal to a maximum of 12 stands from the working stands (from i to i + n) following the crimp (draft) stands, with bulges (5) on sides (4) caliber.
