Integrated monitoring solution to start-up and run-time operations for continuous casting

Abstract Multivariate statistical (MVS) technologies can be applied to both continuous and batch operations for process monitoring and fault diagnosis. Dofasco has developed an on-line MVS monitoring application for its #2 Continuous Caster that combines both continuous and batch MVS technologies into an integrated monitoring solution. Continuous MVS-based monitoring is used for continuous, run-time casting operation. Batch MVS-based monitoring is applied during the start-up operation while the process is in the transition to the run-time operation. This integrated application provides a realtime indication of the stability of the casting operation, which has resulted in improved process safety and economic performance.
