Crosswise uniform cooling system null of the steel strip in continuous system steel strip heat treatment

摘要

The present invention is a steel band cooling apparatus in a vertical path of a continuous steel strip heat treatment process, in which the jet centerline of the cooling medium discharged from the cooling nozzle is located at a position intersecting the steel strip surface in the steel strip width direction of the cooling header disposed close to both surfaces of the steel strip The cooling nozzle is provided with an inclination angle such that the jet centerline is inclined toward both ends of the steel strip with respect to the normal direction of the steel strip.
