AbstractA secondary heating method for the surface of continuously hot-galvanized steel band features that a heater using the liquefied petroleum gas, gas or electricity as energy source is used to generate higher temp at both sides and lower temp at central position for compensating the quick cooling effect of the sides. Its advantages are large-size and uniform zinc pattern on normal settling or small zinc pattern with uniform lustre on quick settling, lower temp of molten zinc, and long service life of equipment.
