<p>The present invention relates to a flux composition for steel galvanization comprising (a) zinc chloride of more than 40 wt% and less than 70 wt%, (b) ammonium chloride of 10-30 wt%, (c) a set of at least two alkali metal chlorides including potassium chloride and sodium chloride of more than 6 wt% and less than 30 wt%, (d) lead chloride of 0-2 wt%, and (e) tin chloride of 0-15 wt%; and provided to change the KCl/NaCl weight ratio of at least two alkali metal chlorides within 2.0-8.0. Moreover, the present invention relates to a fluxing bath including a flux composition dissolved in water for use in galvanizing processes of a metal product such as long steel or a steel product, and a flat product including a wire, a sheet, a coil, a rod, a reinforcing bar, a tube, a strip, and a sheet in batch or continuous operation.</p> |
