Abstract (en)
An inclined-rolling apparatus for piercing and rolling a tube material by the use of a pair of piercing rolls (1R,1L) and a pair of disk rolls (10U,10D), wherein rolling operation is executed with the disk rolls being positioned such that a skew angle ( delta ) opposite to the revolving direction of the tube material (6) is added to the outlet sides thereof and their shaft center lines (12) are inclined. In order to get rid of the interference between the piercing rolls and the disk rolls, there is provided a circular groove at the periphery of a side face of each disk roll. <IMAGE>
