Abstract
PURPOSE:To make possible shaping of high accuracy free from the production of flaws and forming of plural sizes by incorporating the 4-pieces-set roll construction forming an approximately square rolling spacing for the forming rolls used prior to press-roll-piercing of a square slab. CONSTITUTION:A slab 3a is sent from continuous casting process to forming rolls 1a by becoming the shape of an approximately square in shape as shown by the imaginary line 2a. The forming rolls working this are constituted by four of the rolls 1a each having a flat rolling surface 6a pressing the corner part of the slab 3a, as one set. Hence, the rolling space of an approximately square shape is formed by the respective rolling surfaces 6a. Forming is accomplished by driving all of the four rolls 1a or driving the mutually opposing or mutually adjoining two rolls 1a and exerting pushing-in force to the slab 3a, whereby the slab 3a free from crease and flaws owing to roll sliding-down shown in hatching is obtained. This slab 3a is formed to a hollow cylindrical body with a press-roll piercing machine.
