Abstract
Apparatus for finishing a molten metallic coating on metallic strip and sheet comprising means for removing excess molten coating metal by impinging an elongated jet of gas under pressure on opposite sides of the strip and sheet substantially normal thereto. An improved nozzle of high efficiency is disclosed having an elongated plenum chamber communicating directly with a pair of elongated converging lips defining an orifice of about 0.03 to about 0.20 inch, the interior surface of the plenum chamber merging smoothly into each lip with a radius of curvature substantially equal to the orifice opening. The near-field region of the nozzle is about 8-10 times the orifice opening.
