An apparatus for cooling an upper work roll of a rolling mill stand and a strip of metal being rolled has a header to supply a coolant fluid to the work roll and a stripper with a wiper blade that contacts the surface of the work roll between the header and the strip of metal. A fluid cylinder and extension rod cooperate with the stripper to displace the wiper from contact with the upper roll surface and form a gap through which a portion of the coolant fluid flows to contact and cool the strip of metal. A microprocessor and assorted equipment are used to adjust the size of the gap and effect a desired flow of the portion of coolant fluid on to the surface of the strip of metal.

In a rolling mill stand having upper and lower work rolls and having a roll bite through which a strip of metal is passed to reduce the thickness of said strip, with means to cool said lower work roll and a stripper having a wiper arranged to contact the surface of upper work roll across the width thereof, the improvement comprising means for cooling said upper work roll and said strip of metal, prior to entry of the strip of metal between said work rolls, including means for applying a coolant fluid to said upper work roll at a location above said stripper, and means for regulatable variable displacement of the wiper of said stripper away from contact with said roll based upon a sensed condition of the strip of metal so as to direct at least a portion of said coolant onto said strip of metal immediately adjacent said roll bite to cool said strip of metal prior to entry between said work rolls.
