Parameters Influencing the Hot Dip Galvanizing Processes of Sheet Metal

Abstract

Galvanized carbon steel is one of the most used engineering material in industries, but its quality can be affected by the process parameters. The most common used galvanizing process is Hot Dip Galvanizing amongst others. The methods used were quantitative and qualitative for determining the parameters influencing galvanizing. The analytical techniques were performed by spectrometers, visual inspections thru optical and scanning electron microscope which show how parameters at the pickling, cold rolling and galvanizing processes that affect the quality of the galvanized components produced. During galvanizing there are process parameters that need to be monitored, necessitating evaluation of the process parameters that affect the hot galvanizing process. The focus of this paper is on parameters that affect the hot dip galvanizing process from different stages (pre-treatment, galvanizing and post treatment), but especially focused at the galvanizing bath. The quality of the galvanized carbon steel products gets greatly affected by the interference of the process parameters, this can lead to various types of rejects, thus influencing the quality leading to lower production output during the galvanizing process. But good follow ups of the parameters can lead to less defects which eventually increases production efficiency, component effectiveness and profit margins thus increased production of the hot dip galvanizing steels. So there is need to ensure that parameters for galvanizing are in accordance to standards.
