Abstract：Mould breakout prediction system is the main method of mould process monitoring, which can effectively avoid such abnormalities as sticking-type breakout accident, and is of great significance to improve the slab quality and realize high speed continuous casting. For slab continuous casting process, based on the analysis of the thermocouples’ temperature profile history during the breakout process, a new logic judgment model was proposed for sticking-type breakout prediction. And then mould breakout prediction system (MBPS) was developed. The system was applied to the slab casters in H steel plant. The results showed that the system’s detection rate, accuracy rate of prediction and frequency of false alarm for sticking-type breakout are 100%, 78.26% and 0.15% time/heat respectively, which achieved better performance for breakout prediction.
