Abstract
A cooling and lubricating device for rollers of a cold rolling mill with one or more roll stands for controlling strip tensile stress of the strip across the width by changing the effective roll barrel diameter and/or the roller lubrication with a controlled supply of rolling oil or emulsions. The supply is pressure-, quantity-, and/or temperature-controlled. Several nozzle beams are provided and assigned to individual rollers, respectively. The nozzle beams are connected to side shields of the roll housing. Spray nozzles are mounted in the nozzle beams and distributed across the entire roller width. The nozzle beams are moveable independently relative to the rollers transverse to the strip running direction and in planes parallel to the strip plane. Rotary and linear drives are connected to the nozzle beams for rotating the nozzle beams about the longitudinal axis and for moving them in the longitudinal direction.
