Mill stand roll assembly - with control of roll position within gaps between thrust shoulder and thrust discs of hydrostatic bearing

摘要

Mill stand roll assembly comprises grooved rolls each having a thrust shoulder on a roll neck located inside a thrust hydrostatic bearing placed in a chock, secured to a housing. Thrust discs are arranged on both end faces of each thrust shoulder and form with the chock a cavity which communicates via a chock aperture with a source of liq.. Each shoulder has an annular slot coaxial with the corresponding roll for accommodating two washers. Used in section and wire rolling mills. The liq. delivery rate is adjustable w.r.t. the amt. of roll displacement so as to control the mutual arrangement of the rolls directly in the course of rolling.
