Title:
GAS WIPING DEVICE AND METHOD FOR MANUFACTURING MOLTEN METAL PLATED STEEL STRIP
Document Type and Number:
WIPO Patent Application WO/2018/079087
Kind Code:
A1
Abstract:
The present invention provides a gas wiping device which can quickly remove molten metal splash adhered to a slit. This gas wiping device 20 is provided with a cleaning jig 40 having a tip plate 44 having a size that allows the tip plate 44 to be inserted into a slit 33 of a wiping nozzle 30. In addition, a displacement sensor 80 positioned adjacent to the slit 33 detects the presence and position of scattered molten metal in the slit. On the basis of positional information which pertains to the scattered molten metal and is output from the displacement sensor 80, a control unit 70 activates a driving mechanism to move the cleaning jig 40. Specifically, the tip plate 44 is inserted into the slit and moved, in the slit, to the position of scattered molten metal P along the plate width direction X of a steel strip, and the scattered molten metal P is thereby scraped and removed by means of the tip plate 44.
