Modeling on the Two-Phase Flow in a Slab Continuous Casting Strand Using Euler–Euler Approach

The stability of flow field in the mold has a great effect on the quality of the final continuous casting product. In the current study, the multiphase flow in a slab continuous casting strand was systematically studied using a full scale numerical simulation via Euler–Euler approach, and the effect of the operational parameters including casting speed, gas flow rate, and the submergence depth of the submerged entry nozzle (SEN) was investigated. The study showed that the lower casting speed tended to generate more single roll flow in the strand. With the decrease in the gas flow rate, the flow pattern was evolved from a single roll to a complex flow and then to a double roll. For a fixed gas flow rate and a fixed casting speed, the deeper submergence depth generated more double roll pattern in the strand.
