Abstract

PURPOSE:To decrease splash which adheres to the nozzle opening, by, in controlling the molten metal quantity adhered to the nozzle by spraying pressurized gas on the surface of a strip, spraying the pressurized gas while supplying auxiliary gas near the opening in order to prevent the formation of negative press. region. CONSTITUTION:A strip 1 is led into a hot dipping bath 2, where it changes its course to the vertical direction by an inside roll 3. It is then taken out of the bath 2 and the metal adhered to the strip is controlled in a prescribed quantity with pressurized gas sprayed through nozzles 4a, 4b. Guide plates 12a, 12b of circular arc shape are attached to the upper and the under surfaces of the nozzle body 9 by mounting grooves 10a, 10b and guide plate supports 11a, 11b, and an opening is made in the front part of the nozzle 14 between top ends 13a, 13b. Auxiliary gas 18a, 18b led through a gas pipe 16 to auxiliary gas chambers 15a, 15b eliminate negative press. and unite with pressurized gas 19 sprayed through a gas pipe 17 and the nozzle 14. Hereby, the strip 20 is wiped.
