Abstract: Intelligent casting technology has been promoted and applied in continuous casting production.In order to reduce production accidents, stabilize the quality of casting billet, and realize safe production far away from the casting site, an intelligent casting process model was developed and optimized for the unsteady casting process by combining operation experience. In this paper, some intelligent management and control models were studied and applied for continuous casting production, focusing on some key technologies such as the tundish automatic casting model, SEN one-key quick replacement model, and casting anomaly automatic disposal model. The principles, application and effects of the three models were introduced.Through the research and practice of the above models, the success rate of automatic casting reaches more than 95 %, the success rate of automatic SEN replacement is as high as 100 %, the degradation rate of abnormal casting billet defects of SEN change is reduced by 52 %, the personnel on-site duty time is reduced by 50 % after the automatic disposal of casting anomalies, and efficiency of personnel is increased by about 10 %.The intelligent production process and stable casting quality are promoted.
