Performance observation of hot dip galvanization for steel sheets

Abstract

Galvanization is a widely applied surface treating technology to improve the sheet metal finish and life also. Hot-dip galvanization is performed in a confined atmosphere of the laboratory with steel sheet metal samples of 0.20, 0.60, and 1.0 mm respective thicknesses. The experiments are carried out having 99.8% of zinc and 0.2% of aluminum at 450 °C temperature for one minute immersion period at extraction speeds of 3, 4, and 5 m/min, respectively. The samples are introverted into a dirt-free area and are rapidly cooled with a suitable medium. The class of the galvanization was observed by its exterior, luster, and consistency. The outcome shows variations in its quality with the variations in parameters and different thicknesses of the undertaken samples. The sample gauges, i.e., 18, 22, and 28, represent the best quality of observations having effective luster and uniformity at the extraction speeds of 3, 4, and 5 m/min, respectively. The variations in temperature and gauges have different cooling times and result in observations accordingly.
