With cleaning gas.Apparatus for applying and continuously monitor the thickness of a metallic coating applied to the surface of a wire material and process to control the thickness of a coating on airLove from a bath of molten coating

摘要

A gas wiping die for wiping wire issuing from a molten metal coating bath is provided with critical parameters with respect to the die angle, the length and thickness of the die orifice and the relationship of the sides of the orifice, the throat diameter of the die and the height above the molten bath surface. The thickness of molten coatings on wire wiped with the combined die can be very accurately controlled by changes in wiping gas pressure. IMAGE
