Abstract
Exemplary embodiments of the invention include a method and apparatus for cooling a metal strip that is being advanced in a generally horizontal fashion. The method involves delivering a coolant liquid onto a lower surface of the strip from below across the entire width of the strip, preventing the coolant liquid from contacting the upper surface of the strip, and optionally subsequently removing the coolant liquid from the lower surface. The coolant liquid is prevented from contacting the upper surface by forming a gas-directing channel immediately above the upper surface of the strip adjacent to one or preferably both lateral edges of the strip and forcing a gas through the channel in a direction generally away from a center of the strip towards the one or both lateral edges to deflect coolant liquid away from the upper surface of the strip. The apparatus provides means for carrying out these steps.
