Screw rolling in pipe production was first used by Mannesman. In this process, the blank passes between two rollers that are inclined at an angle to the rolling axis and turn in the same direction. In this case, the velocity of the metal in the deformation source has axial and tangential components, and the blank turns as it moves axially. Further study of the screw-rolling method in three-roller cells shows that this method is effective in producing rods of complex cross section. At the All-Russian Institute of Metallurgical Machinery [1], a technology for periodic rolling of nonhollow profiles was developed. In this technology, an axial force is applied to the blank. Later, a screw-rolling method was developed at the Moscow Institute of Steel and Alloys. In this case, a relatively large tensile force is transmitted to the blank in the course of roller deformation, with no need to apply an additional external load [2].
