Hot-dip galvanizing annealing process has an important impact on the mechanical properties of hot-dip galvanized sheet. Developing a reasonable annealing temperature system and precise control of the plate temperature have become the core issues in the precise annealing process of hot-dip galvanized sheets. Based on the analysis of the influence of annealing process on the performance of hot-dip galvanized sheet, a method based on data-driven annealing process is proposed to overcome the deficiencies of existing annealing process. This method can achieve continuous optimization of hot-dip galvanized sheet annealing process. At the same time, a systematic overview of the current temperature control strategy of the model-based hot-dip galvanizing annealing process is proposed. According to the characteristics of the hot-dip galvanizing process, a temperature control method of hot-dip galvanizing annealing process with high applicability data and physical model is proposed. To achieve the precise heat treatment of hot-dip galvanized sheet.
