Abstract
PURPOSE:To make the sectional shape of the rolled product controllable to the optimum condition easily and economically, by making adjustable within the horizontal plane the crossing angle of the axes of the upper roll group and the axes of the lower roll group, both possessing their axes within the same vertical plane different from each other group. CONSTITUTION:When the rolling work for the rolling material 11 is started, the axes 16, 17, of the upper roll groups 12, 13, being located within the same vertical plane, and the axes 16', 17', of the lower roll groups 12', 13', being located within the same vertical plane different from the vertical plane of the upper roll group axes, cross each other by the crossing angle theta, which is adjustable to any arbitrary desired value. Besides, since both ends of upper and lower work rolls 12, 12', are constituted so as to be impressible with the bending force, the optimum sectional shape of the rolled material 11 can be very easily formed. Moreover, according to this constitution, the wear of the rolls is diminished, and the number of rolls is smaller as compared with the six-stage rolling mill so that the rearrangement work for rolls is easy.
