    • 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.
    • 一种用于将熔融金属涂覆到钢带上的气体擦拭装置。 在该装置中,供应高压气体的腔室限定了多级统一的压力空间。 唇支撑单元与腔室的前部相关联,以允许高压气体流过其中,唇支撑单元支撑装置抵抗负载。 上唇和下唇与唇支撑单元的前部相关联,以协作地限定出口。 上唇与下唇协调地调节气体出口的间隙,并且可以容易地安装在唇支撑单元中,同时稳定地调节气体出口的间隙。 此外,可以防止钢带的边缘涂覆(EOC),而无需附加辅助喷嘴。
