With ANSYS CFX’s advanced modeling techniques, the engineer can easily investigate and understand those issues which affect caster performance and product quality. Wave formation and turbulence at the free surface can be predicted and the design of the pouring system optimized to prevent entrapment of the slag layer and draw-down of particles. CFX’s multiphase models can be used to study how gas injected in the submerged entry nozzle is distributed within the mould and its effect on the flow of the molten metal.
Solidification of the strand can be simulated using models that include latent heat evolution and Darcy resistance treatment of flow through the mushy region. The predicted solidification rate, development of the solid shell and contaminant particle inclusion profiles are all vital pieces of information for the operator when assessing the performance of continuous casting plant.
