FIELD: metallurgy.
SUBSTANCE: invention relates to pressure-bearing hydraulic unit of rolling mill, particularly to installation cylinder for rapid installation of forming rolls in rolling mills, inter alia in vertical breakdown rolling mills. Installation cylinder contains at least one plunger for influence otth through bolster, at least one working roll or one intermediate roll on working roll, herewith plunger is outfitted by two turned into side opposite rods and passing, correspondingly, through the bottom of cylinder and cover of cylinder , in which there are implemented co-axial located holes for passing of piston rods, herewith surface which is formed by piston and the first rod allow less dimension then surface formed by piston and the second piston rod.
EFFECT: it is provided higher conveying speed with the same pump productivity.
