Abstract
PURPOSE: To make possible the manufacture of titled pipe with various sizes from the bloom of large section, by specifying the sectional area, outer diameter, wall thickness, of the blank obtained from the polygonally sectioned bloom, by preparing the cylindrical blank from above blank with the press roll piercer, by reducing diameter of this cylindrical blank with two cross helical rolling mills, and by finishing with the finishing mill.
CONSTITUTION: After heating the polygonally sectioned metallic bloom of sectional area A to a suitable temperature by the furnace 1, this bloom is supported by the mandrel, and is pushed into plural round roll calibers of the press roll piercer 2; hereby, the cylindrical blank, being bottomed at one end and bottomless at another end, is prepared. Hereupon, the outer diameter of the blank after being worked is specified to 1.1 root AW1.2 root A, and the wall thickness is specified to 0.2 root AW0.3 root A. Next, the pipe blank P is rolled by the cross herical rolling mill 3 so as to reduce the outer diameter to 0.6W0.9 times, and wall thickness to 0.10W0.25 times of outer diameter reduced by the rolling work. After that, the outer diameter of the pipe blank is reduced to 0.7W0.9 times by the cross helical rolling mill 4 under a specified condition, without inserting the plug, mandrel, etc., into the blank. This pipe blank is rolled by the mandrel mill 5, is heated to a suitable temperature, and then finish rolled by the stretch reducer 9.
