Method of cooling a coating and device for conducting the process, separated continuously by hot dipping on a wire, strip or other profile

摘要

An apparatus for cooling a coating on a wire comprising three separate coaxial passages through which the wire is adapted to pass after coating, the first and second passages passing through the walls of a pressurized gas manifold, the third passage having a tangentially directed liquid inlet bore therein and being flared at its lower end to define a liquid outlet passage between its lower end and the upper end of said second passage, means supplying liquid to said bore at such a rate as to cause a steady helical flow of liquid which fills said third passage but flows primarily from said outlet passage, and means supplying gas to said manifold at a pressure sufficient to cause substantially all of said quenching liquid to flow through said outlet passage.
