Optimization of Thickness by Design of Experiments and Energy-Saving Techniques for Industry 4.0 in Galvanization Process: Literature Survey

This study provides an organized review of several aspects of the hot-dip galvanization (HDG) process. Over the last few decades, there has been rapid advancement in the HDG method for industry 4.0 in the galvanization process, as well as two major issues with galvanized product quality and excessive resource utilization. In contrast to zinc loss and increased energy consumption, which are classified as excessive resource consumption, microstructure, and coating layer aspects have all been identified as difficulties related to standard. Most of the problems were created by the chemistry of steel and the zinc bath kettle. Temperature, immersion time, and alloy chemical composition all have a substantial impact on the microstructure, coating thickness, and corrosion resistance of a zinc bath coating. These three chemicals behave differently on different silicon-containing steels. This review study thoroughly considers all three of these criteria to investigate and appreciate the HDG influencing elements and their impact. Many researchers have identified DOE as a favorable method for HDG enterprises to embrace and examine to achieve effective resource utilization while improving product quality.
