Abstract
PURPOSE:To control the amount of metal of the bulb part, by adjusting the rolling by shifting the horizontal roll downward in a distance necessary for reducing wall thickness, at the accomplishment of the universal rolling work to obtain the straight sheet reduction pile. CONSTITUTION:The vertical roll is employed for rolling in the longitudinal direction at the universal rolling work to obtain the straight sheet pile. Hereby, the amount of metal of the bulb part A scatters and the length l of the part lower than the bulb part A fluctuates. As the countermeasure for preventing these troubles, the horizontal rolls 1, 2, are shifted downward in a distance necessary for reducing the wall thickness for the purpose of equalizing the breadth to of the bill B to breadth tw the web C and making breadth td of the bulb A small; thus the rolling reduction is adjusted. Hereby, the part A equivalent to the bulb part is formed, in which the metal bulges by a specified amount outward directing from the part B equivalent to the bill to the web C, and also, the metal is extended almost straight in the direction opposite to the part B equivalent to the bill. Then, the material is successively rolled by the calibers K-4E, K-3, K-2, K-1, and the desired straight sheet pile is obtained.
