Features: This book comprehensively elaborates on the fundamental theories, production processes, products, and advanced technologies of modern continuous hot-dip galvanizing of steel strips. The main contents include the development history and latest advancements in the technology of continuous hot-dip galvanizing of steel strips; the principles of corrosion resistance of galvanized steel plates, the theory of continuous hot-dip galvanizing of steel strips, and the factors affecting the coating thickness, structure, and performance; the original plates used in continuous hot-dip galvanizing, the cleaning technology of hot-dip galvanizing base plates, the continuous annealing technology of hot-dip galvanizing units, and the hot-dip galvanizing kettle, heating methods, zinc kettle equipment, and operations during the hot-dip galvanizing process. It focuses on introducing research hotspots such as the study of automotive coated steel plates and alloyed hot-dip galvanizing theory, the development of alloyed hot-dip galvanizing coating materials, alloying treatment equipment, and coating alloying control technology. Additionally, it covers the processes and characteristics of continuous hot-dip galvanizing for hot-rolled steel strips and single-sided steel strips, as well as the post-treatment of steel strip hot-dip galvanizing, including cooling, spangle removal, pickling, leveling, oiling, passivation, phosphating, and coating. Furthermore, it details the main mechanical equipment of continuous hot-dip galvanizing units, environmental protection, and the treatment of "three wastes," as well as the performance testing, defect analysis, and process simulation of hot-dip galvanized steel plates. The appendix also introduces the standards for quality testing of galvanized steel plates domestically and internationally, as well as the construction of continuous hot-dip galvanizing units by major domestic steel producers. This book is a valuable reference for researchers, decision-makers, managers, and technical personnel involved in the deep processing of steel products, the production and application of hot-dip galvanized steel strips (plates), technical personnel in research and design units, and faculty and students in relevant fields at universities.
