According to the two types of slab defects (surface crack and internal crack), a real-time slab quality diagnosis and analysis system named CISDI_SQDS ONLINE R2011 was developed based on heat transfer and solidification simulation, stress and strain calculation as well as metallurgical process analysis about continuous casting, combined with expert knowledge database for specific casting events. The respective crack formation indexes were introduced as the theoretical reference data for slab quality level evaluation. Meanwhile, both the quality loss factors related to casting metallurgical rules and the adjusting factors related to casting events were taken into full consideration, which was integrated organically with theoretical analysis and expert system. The system can be widely used as an important theoretical tool for prediction and control of slab quality in slab continuous casting process. © 2013 Central Iron and Steel Research Institute.
