Abstract

PURPOSE:To improve the effectivity of a crown roll in controlling the sheet crown, by constituting either one backup roll of a four-high rolling mill as a crown roll, and making the diameter of a work roll on the side of this backup roll smaller than that of another work roll. CONSTITUTION:In a four-high rolling mill, a crown roll V is employed as an upper backup roll, for example. That is, a cylindrical clearance is formed between an arbor 1 and a sleeve 2 of the said backup roll, and a pressure medium is introduced into this clearance, and thereby, the backup roll becomes a roll V-B provided with a crown-variable construction. The diameter of a work roll W-2 contacting with this backup roll V-B is made smaller than that of another work roll W-1. By the present constitution, the bending stiffness of the work roll W-2 becomes small, so that the effectivity of the crown of the backup roll V-B, in controlling the thickness distribution of a material 3 through the work roll 2, is improved.
