Patent number: 8113139Abstract: 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.Type: GrantFiled: December 12, 2006Date of Patent: February 14, 2012Assignee: PoscoInventors: Gun Young Kim, Hae Doo Park, Dong Eun Lee, Won Cheol Chung

Patent number: 8047718Abstract: In a bearing device for a roll of a hot dipping bath, i.e., zinc pot, a sleeve is fastened to a shaft of the roll of the hot dipping bath in a continuous hot dip coating line, i.e., a continuous galvanizing line. A bush housing has a bush internally fixed to support the sleeve, and a curved annular outer surface. Also, bush housing fixed rings are fixed to both inner sides of a fixed ring housing which is associated with a rig of the hot dipping bath roll. Each of the bush housing fixed rings has a curved annular inner surface supporting the bush housing at both sides thereof and in abutment with the curved annular outer surface of the bush housing. The invention allows the steel sheet to be coated with molten metal stably and speedily with high efficiency. Also, the bush and sleeve of the bearing device are not locally worn away, thereby extending useful life of the roll.Type: GrantFiled: December 15, 2006Date of Patent: November 1, 2011Assignee: PoscoInventors: Gun-Young Kim, Yung-Up Kim, Hong-Jong Yoo, Gyn-Sam Hwang
