<p>#CMT# #/CMT# The process comprises passing the metallic band in a molten metal bath, spin-drying the coated metallic band using nozzles that project a gas on the band, and cooling the coating surface in a controlled manner until the complete solidification is obtained. The cooling is conducted at a speed of lower than 10[deg] C/s between the temperature of spin output and the beginning of solidification, then at a speed of >= 20[deg] C/s between the beginning and end of the solidification. The molten metal bath is maintained at a temperature of 350-700[deg] C. #CMT# : #/CMT# Independent claims are included for: (1) a laminated metallic band, which is cooled and coated; and (2) a metallic part obtained by deformation of a metallic band. #CMT#USE : #/CMT# The process is useful for the fabrication of a metallic band such as steel band having a metal coating for protection against corrosion (claimed), where the steel band is useful as skin part for land motor vehicle. #CMT#ADVANTAGE : #/CMT# The process is capable of economically and energy efficiently fabricating the metallic band with good surface appearance, and provides increased protection against corrosion to the vehicles. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The molten metal bath comprises 2-8 wt.% of aluminum, 0.5 wt.% of magnesium and 0.3 wt.% of additional elements, zinc and unavoidable impurities.</p> |
