Abstract

PURPOSE: To perfectly correct the shape of a metallic strip, by constituting the work roll so as to internally hold a fluid pressure, and by adjusting the fluid pressure for adjusting the work roll's crown.
CONSTITUTION: When the fluid pressure of the pressure chamber 3 is null, the diameter of middle of the outer shell 1 of the roll becomes smaller than that of both ends of the outer shell 1 so that a concave crown is formed. With increase of the fluid pressure, this concave crown gradually lessens, and sooner or later a flat roll practically unpossessing any crown is formed. If the fluid pressure is further raised, a convex crown is formed in the roll. Accordingly, the roll crown can be freely adjusted from concave to convex by adjusting the fluid pressure. Though the air, water, oil, etc., are available for the fluid, the oil is desirable to employ by the reason of easiness in obtaining the high pressure power.
