SUMMARY:Virtual continuous casting for improved processes with MAGMA CC
DESCRIPTION:Today, simulations for improving process conditions and the quality of continuous cast products are a generally accepted tool. 

State of the art simulation tools provide quantitative insights into the flow, solidification and stress formation in continuous casting processes. This includes the entire casting process, starting from the tundish and the flow into the mold, up to the solidifying strand, that is withdrawn through various cooling zones. This provides important information about quality and productivity when evaluating process alternatives. 

The classical use of simulation solutions has evolved to a higher degree of automation and virtual process optimization. Usage of digital twin technology in combination with integrated statistical tools enables a systematic virtual testing to identify an ideal process window. 

This enables the expert to identify the significant process parameters and to investigate the level of their influencing effect, without performing expensive and time-consuming trials on the shop floor. Based on this knowledge, it is possible to optimize continuous casting processes that are both, cost-effective and robust with respect to process variations. 

This paper will discuss the modelling of modelling of electromagnetic stirring (EMS) and its impact on the flow behavior in the strand. Another focus will be the evaluation integrated stress calculation to avoid the formation of cracks. Stress simulation is also used to described the gap formation in the mold and the corresponding change of primary cooling conditions. 

The results are shown using industrial examples for a bloom caster. With the availability of the integrated process knowledge of a digital twin, it is possible to identify optimal operating points for quality improvements and productivity increases. The objective is to derive a comprehensive model for online monitoring and optimized dynamic online control of the cooling and solidification process.
