Gas Wiping Apparatus Having Multiple Nozzles
Abstract: A gas wiping apparatus is a type of equipment for coating a molten metal onto a steel strip, in which the molten metal solution deposited on the steel strip is wiped to adjust a coating thickness. The gas wiping apparatus includes a body containing a high pressure gas and a multiple nozzle unit disposed at the body to eject the high pressure gas onto a surface of a moving coated steel strip. The surface of the coated steel strip passing through a hot dipping bath filled with the molten metal is wiped by a high speed gas jet. Here, the molten metal is prevented from splashing even at a high-speed and the steel strip can be adjusted in the coating thickness stably and uniformly.
