Continuous casting

Highlights

• The iron alloy database (IAD) was developed further to provide data for solidification calculations.
• Phenomena-based quality indices were proposed for predicting the onset of defects in slabs
• A coupled workflow including heat transfer simulation, solification simulation and machine learning was developed for online prediction of defects in continuous casting of carbon steels.
