The centerline quality of a continuously cast slab is one of the major quality indicators for further downstream processing to manufacture defect-free final products. Monitoring of centerline quality during casting can be approached either by direct measurement of the solidification front position or by online dynamic simulation based on a verified solidification model. ArcelorMittal Global R&D East Chicago Laboratory developed a dynamic solidification model to control secondary cooling for optimal slab surface temperature. One of the features of this model is the calculation and graphical display of liquid core position within the caster each 5 seconds. The model calculates the thermal distribution for 250 slices within the caster every 5 seconds. Each slice has its own thermal history and therefore during heavy speed transition cases (tundish fly, SEN change, ladle change or breakout prevention), the model takes into account the longer residence time of the slab inside the machine. These transition events can cause bridging inside the slab and centerline unsoundness will appear. This paper will present results of the model simulations during large casting speed changes on solidification behavior and quality. Furthermore possible countermeasures to prevent these undesired effects during speed changes will be discussed.
