Abstract
PURPOSE:To easily produce a colored galvanized steel sheet having excellent appearance and paint adhesiveness and desired color tones by spraying Zn alloy powder contg. a metal element having a coloration effect on the surface of a galvanized steel sheet in an unsolidified state right after hot dip zinc coating thereby forming a colored oxide film thereon. CONSTITUTION:The steel sheet 1 is galvanized in a hot dip zinc coating bath 2 and thereafter, the coating weight is controlled by a gas wiper 3. The Zn alloy powder contg. the metal element having the coloration or color assisting effect is then sprayed by a spraying device 4 to the steel sheet in the position where the galvanizing is not solidified. This steel sheet is oxidized in an oxidizing atmosphere in a heating furnace 5 to form the colored oxide film on the surface thereof and is cooled by a jet cooler 6. The colored steel sheet 1' is cooled with water in a water jet cooler 7 and is dried in a dryer 8; following which the steel sheet is treated by a chromate treatment device 9 and a clear treatment device 11, respectively.
