Abstract

PURPOSE:To freely form a convex crown and a concave crown in outer surface of sleeves, by giving a concave crown to outer surface of sleeves, and by a little shifting sleeves in the axial direction. CONSTITUTION:Convex crowns 4a, 5a are given to a half one side of the outer surface of backup rolls 4, 5; correspondingly to these convex crowns 4a, 5a, the concave crowns 6a, 7a in the same shape as 4a, 5a are given to the inner surface of sleeves 6, 7; besides, the concave crowns 6a, 7b are given to a half one side of the outer surface of the sleeves 6, 7. The sleeves 6, 7 are shifted by X0 to the left and right respectively against the backup rolls 4, 5 in order to make a gap DELTAy. When a rolling load is loaded on the contact surface between the sleeves 6, 7 and the work rolls 2, 3, the sleeves 6, 7 deflect inwards because of the gap DELTAy, so that the inner surface of the sleeves 6, 7 contacts with outer surface of the backup rolls 4, 5. Hereby, a crown, as a sum of a convex crown equivalent to DELTAy and the concave crowns 6b, 7b formed in outer surface of sleeves 6, 7, is formed in the contact surface between sleeves 6, 7 and work rolls 2, 3.
