Abstract
Rapid cooling section of a continuous metal strip treatment line, where the strip is cooled with a spray of liquid or a mixture of gas and liquid using nozzles located on each side of the strip. Along the direction of movement of the strip, it includes at least one row of flat spray nozzles across the strip followed by at least one row of cone spray nozzles across the strip.
Claims12
A method of rapidly cooling a continuous metal strip treatment line, comprising:
- cooling the strip with a spray of liquid or a mixture of gas and liquid using nozzles located on each side of the strip in relation to its plane of movement;
- wherein along the direction of movement of the strip, the method comprises at least a spray from a row of flat spray nozzles, followed by at least a spray from a row of cone spray nozzles, with the nozzle rows arranged transversely in relation to the plane of movement of the strip;
- and
- wherein in the direction of movement of the strip, at least one row of flat spray nozzles which are single fluid, at least one row of cone spray nozzles which are single fluid, the rapid cooling section further including at least one row of flat spray nozzles which are dual fluid and followed by, in the direction of movement of the strip at least one row of cone spray nozzles which are dual fluid, the row of nozzles located transversely to the plane of movement of the strip, the single fluid nozzles arranged to spray a liquid on the strip and the dual fluid nozzles arranged to spray a mist made up of a mixture of gas and liquid on the strip.
