  • Widthwise uniform cooling system for steel strip in continuous steel strip heat treatment step
    Patent number: 6054095
    Abstract: The present invention is to provide a cooling system for cooling a strip in a vertical path of a continuous strip heat-treating process in which cooling nozzles are arranged in a width direction of a strip on the surfaces of cooling headers arranged closely opposed to both surfaces of the strip, and each cooling nozzle is inclined to both edge portions in the width direction of the strip by an inclination angle in such a manner that a center line of a jet of a cooling medium, which is jetted out from the cooling nozzle, is inclined with respect to a normal line at a position on the strip surface where the center line of the jet of the cooling medium crosses the strip.
