Abstract
A cooling and lubricating device for a cold rolling mill has nozzle beams with spray nozzles for individual rollers that are moveable relative to the rollers independently of one another transverse to the strip running direction. Rotary and linear drives are connected to the nozzle beams for rotating them about the longitudinal axis and moving them longitudinally. The nozzle beams are movable from a maintenance position to a working position and back. The spray nozzles have nozzle holders mounted in openings of the nozzle beams and nozzle heads mounted in the nozzle holders. Rotary slide valves with control members are rotatably supported in center throughbores of the nozzle holders. The rotary slide valves have blind bores opening to the nozzle heads and inlet openings aligned with inlet openings of the nozzle holder or nozzle head, when the spray nozzle is open, and covered by the nozzle holder or nozzle head, when the spray nozzle is closed.
