  • Patent number: 8151728
    Abstract: A gas wiping apparatus for use in coating a molten metal onto a steel strip. In the apparatus, a chamber, to which a high pressure gas is supplied, defines a multistage uniform pressure space. A lip support unit is associated with a front of the chamber to allow the high pressure gas to flow therethrough, the lip support unit supporting the apparatus against load. Upper and lower lips are associated with a front of the lip support unit to cooperatively define an outlet. The upper lip adjusts a gap of a gas outlet cooperatively with the lower lip, and can be easily installed in a lip support unit while adjusting the gap of the gas outlet stably. Also, edge over coating (EOC) of the steel strip can be prevented without an additional auxiliary nozzle.

  • Patent number: 8113139
    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.
