Contained quench system for controlled cooling of continuous web

摘要

A method and apparatus for continuously cooling a moving web while simultaneously removing the cooling fluid from the web in which a stream of quenching fluid is applied transversely across the web to cool it and a fluid containment gas is positioned on either side of the quenching fluid to direct a containment fluid toward the quenching fluid and establish a continuous containment fluid curtain stream to prevent passage of the quenching fluid beyond the point of which the containment fluid is introduced.
