Abstract

PURPOSE:To make the sheet crown controllable in accordance with a wide variation in the sheet breadth, by employing a sleeved roll having a pressure fluid pocket as a backup roll, and by permitting a work roll to shift in its axial direction. CONSTITUTION:In a four-stage rolling mill capable of controlling the sheet crown of a rolled material, a sleeved roll having a pressure fluid pocket 3 is employed as a backup roll. A sleeve 1 is fitted on outside of an arbor 2 of the backup roll; a sealing mechanism and a fixing mechanism are respectively provided at the fitting planes on both ends of the sleeve 1. An initial crown is given to a drum end of each of upper and lower work rolls at symmetrical positions. When the breadth of the rolled material is changed, the work rolls are shifted in their axial direction to a position whereby obtainable a proper sheet crown, while holding a point symmetry. By the present constitution of the rolls, the correcting capacity for the sheet crown is greatly improved even against a rolled material of a narrow breadth.
