摘要： A gas wiping apparatus is a type of equipment for coating a molten metal such as molten zinc onto a steel strip. In the gas wiping apparatus, a lip defines a gas outlet for ejecting a high- pressure gas to adjust a coating amount on a steel strip. A metal chip removing unit includes a metal chip remover disposed inside the lip to remove metal chips from the gas outlet and a drive unit associated with the metal chip remover to drive the metal chip remover along the gas outlet. A metal deposition prevention layer is formed on a surface of the lip around the gas outlet, the metal deposition prevention layer having a surface roughness up to 0.5µm. Thus, the gas wiping apparatus including the metal chip removing unit or the metal deposition prevention layer prevents the steel strip from defective coating caused by the metal chip. The gas wiping apparatus effectively removes zinc chips (metal chips) which are splashed from the surface of the steel strip and deposited on a gas outlet. Also, the gas wiping apparatus has a metal chip removing unit installed therein and prevents a lip around the gas outlet from con¬ tamination by metal chips. This eventually prevents non-uniform coating of the steel strip and shortening in useful life of the apparatus due to the metal chips.

摘要： A gas wiping apparatus is a type of equipment for 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. Meanwhile, a multistage uniform space is defined by the chamber and the lip, allowing the high pressure gas to be ejected more uniformly in response to a high pressure gas ejection profile. This eventually enhances coating quality of the steel strip.
