Abstract
A header for applying a low pressure, non-turbulent, coherent curtain wall of coolant of a substantial uniform extent and thickness transversely across the rolling surface of a work roll of a hot rolling mill or the like, which curtain wall in cross-section is in the form of the uniform concentric enveloping camber of a portion of a roll barrel. The placement of the applied wall of coolant is controlled so that the built-up heat in each succeeding work roll portion leaving contact either with the hot material being rolled or its associated back-up roll in a multi-high mill is substantially and uniformly removed, and optimized cooling thereof is achieved. An adjustable discharge slot which may be tapered to discharge the curtain wall across the length of the roll's camber in a manner to control cooling of the work roll from end to end, i.e. the cooling rate of the length of a roll would have a parabolic curve.
