Abstract
PURPOSE: To prevent the oxidation of the inside surface of the blank pipe with the mandrel having been mounted at the time of piercing held as it is , reduce mandrel mounting and dismounting time and economically produce the seamless steel pipe of high quality by rolling said blank pipe with an elongator.
CONSTITUTION: The blank pipe which is held mounted with the mandrel having been used in a press roll piercing machine 3 is fed as shown by the arrow BM2 then it is fed to an elongator 11 according to the arrow B2' or arrow B2" (a through- hole piercing press device 12 is disposed on the way). Thence, the mandrel fed integrally with the blank pipe like the arrow BM3 is separated from the blank pipe by a draw-off device 17 and this is sent in the arrow M4 direction by a mandrel returning device 19. In the way, it is corrected of bend or the like by a leveling device 20, after which it is circulation-fed to the press roll piercing machine 3.
