Method and apparatus useful in cooling hot strip

摘要

A method of and apparatus for controlling the flow of cooling water to the top of a hot metal strip on a runout table is disclosed. Cooling water is continuously discharged from nozzles in spray bars above the strip and cooling is controlled by selectively diverting the water from selected ones of the spray bars to control the volume and location of the water applied. Movable deflector plates are mounted adjacent predetermined spray bars and actuators are provided to selectively move the deflector plates to deflect water into a fixed trough to be diverted from the top of the strip.
