Abstract

PURPOSE: To surely, easily and rapidly control the profile of an upper rolling roll over a wide range by making both diameters of the upper rolling roll and lower rolling roll equal, also making the profile of the upper rolling roll constant in the axial direction and making the profile of the lower rolling roll into a crown shape such that the roll diameter of the middle part is larger and the roll diameters of both ends are smaller or into a flat shape.
CONSTITUTION: Both the diameters of the upper rolling roll 31 and lower rolling roll 32 are made equal, also the profile of the upper rolling roll 31 is axially made constant, the profile of the lower rolling roll 32 is made into a crown shape such that the roll diameter of the middle part is larger, the roll diameters of both ends are smaller, or into a flat shape and a support roll with the circular shaped section is arranged so as to bring into freely rotatable contact with the upper outer peripheral surface. When using the rolling mill 20, the upper rolling roll 31 is freely adjustable from convex to concave by bending force and this mill possesses the extremely wide range of the capacity of shape control and crown control.
