Title:
METHOD FOR MANUFACTURING MOLTEN METAL PLATED STEEL STRIP AND CONTINUOUS MOLTEN METAL PLATING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/012132
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a molten metal plated steel strip, the method being capable of sufficiently suppressing the generation of flow lines and manufacturing a high quality molten metal plated steel strip at a low cost. The method for manufacturing a molten metal plated steel strip of the present invention is characterized in that when blowing gas from a pair of gas wiping nozzles 20A, 20B onto a steel strip S drawn up from a molten metal bath 14 and adjusting the adhesion amounts of the molten metal on both surfaces of the steel strip S, the angle formed between the ejection port portions of the gas wiping nozzles 20A, 20B and a horizontal plane is between 10 degrees and 75 degrees inclusive, and the header pressure of the gas wiping nozzles 20A, 20B is less than 30 kPa.
