摘要： A tube manufacturing method, comprising a step for rolling a tube at a fixed diameter by using an apparatus for fixed diameter rolling formed of a plurality of stands having a plurality of hole type rolling rolls. The method is characterized in that, where the minimum value of angles formed by the tangents drawn on the opposed edge parts of the hole type rolling rolls adjacent to each other in all stands is beta (deg), the outer diameter of the tube on the out-side of the apparatus for fixed diameter rolling is D (mm), and the wall thickness of the tube on the out-side of the apparatus for fixed diameter rolling is t (mm), such a hole type rolling roll that the angle beta can fulfill the requirement of the following expression (1) is used. beta >= 1.13 x 10 x Ln (t/D x 100) + 1.37 x 10 ...

摘要： A method and a device for controlling the fixed diameter rolling of a tube. The fixed diameter rolling control method for the tube controlling the rotational speed of rolling rolls (21) disposed on stands when the tube end part of the tube (1) is rolled by the stands (2) of a fixed diameter rolling mill is characterized in that the rotational speed control start times of the rolling rolls set for the specific stands are corrected based on the measured value of the wall thickness of the tube end part of the tube measured on the out-side of the fixed diameter rolling mill.
