[0035] Figure 1 to Figure 5 An example of an apparatus for removing impurities from a molten metal surface in a steel sheet hot-dip galvanizing process according to the present invention is illustrated.
[0036] Referring to the accompanying drawings, an apparatus 10 for removing impurities from a molten metal surface in a steel sheet hot-dip galvanizing process according to the present invention is installed in a hot-dip galvanizing bath 150 to prevent the surface of a steel sheet 200 heat-treated at a high temperature from Oxidizes when the steel plate 200 is exposed to the atmosphere. In addition, the apparatus 10 has a structure for preventing surface defects from occurring due to ash, which is formed by condensing vapor of a hot-dip galvanizing solution and adheres to the surface of the steel sheet 200 as impurities.
[0037] The apparatus 10 for removing impurities from a molten metal surface in a steel sheet hot-dip galvanizing process has a nozzle portion 40 having a...
