ABSTRACT:
The invention relates to rolling, and more particularly, to a mill stand roll assembly comprising grooved rolls. A thrust shoulder for each of the rolls, formed on a roll neck, is located inside a thrust hydrostatic bearing placed in a chock secured to a housing. Each thrust has disks each being arranged on both end faces of each thrust shoulder in parallel thereto and forming with the chock a cavity communicating via an orifice in the chock with a source of liquid. Each thrust shoulder having an annular slot coaxial with the corresponding roll for accommodating two washers secured to a chock in a parallel and spacial relationship with one another. A hole in the chock is disposed so as to permit a flow of liquid to pass between the washers. The liquid delivery rate is adjustable with respect to the amount of roll displacement and the roll assembly makes it possible to adjust the mutual arrangement of rolls directly in the process of rolling.
