Intelligent drying strategy for ultra-thin ceramic sheet casting based on infrared perception

Abstract Currently, the setting of cast drying conditions relies more on the experience of engineers, lacking effective methods for quantitative testing and intelligent control. In this paper, the actual drying process of ultra-thin ceramic sheets using infrared perception during the high-speed casting was investigated. The influence of different drying conditions on the microstructure and properties of ceramic sheets was clarified. The infrared perception results show that there are significant differences between the actual temperatures and the set values. Compared to the set temperature, there is a stronger correlation between the actual temperature and sheet properties. The constant temperature drying period is critical for the formation of sheet microstructure and properties. Finally, a general intelligent drying strategy is proposed to meet the diverse needs of the sheet.
