Apparatus for spraying an air-water mist cooling for use in continuous metal casting

摘要

An exhaust hole is formed in an exhaust side wall of a mist atomizing nozzle of an apparatus for spraying the mist for cooling for and is used in continuous metal casting. An introduction inlet is provided in an introducing side wall on the side opposite the exhaust side wall at the height position different from that of the exhaust hole. An air-water mixture supply pipe is attached to the introduction inlet to communicate therewith. The air-water mixture of relatively large water droplets is formed and is introduced into the mist atomizing nozzle by that air-water mixture supply pipe. After the air-water mixture repeatedly collides in the mist atomizing nozzle, the large water droplets are made fine and are sequentially exhausted from the exhaust hole by being pressed by the supply pressure from the rear side.
