ABSTRACT:
A method and apparatus are disclosed for reducing spangle in a galvanization system that utilizes air knives to control coating thickness and distribution. Cooling nozzles are located downstream of the air knives along the feed path of the substrate being coated. The cooling nozzles direct an air and water mixture against the substrate at approximately the location the air from the air knives impinge the substrate. The air from the air knives force the air and water mixture to be carried along the substrate surface in a direction of the substrate feed path.
