Roll and strip cooling system for rolling mills

摘要

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.
