  • Nov 2011
This paper presents a mathematical model and numerical technique for simulating the two-fluid flow and the meniscus interface movement in the electromagnetic continuous steel casting process. The governing equations include the continuity equation, the momentum equations, the energy equation, the level set equation and two transport equations for t...

... (1) -(16) constitute a system of ten partial differential equations in terms of six coordinates and time-dependent unknown functions v x , v y , v z , p, T and φ and four time-independent unknown functions A = (A x , A y , A z ) and ϕ. To completely define the problem, we specify the boundary conditions for the velocity field, temperature field, level set function and EM field as shown in Figure 1. 3. Method of Solution. The electromagnetic field problem as shown in section two can be uncoupled from the two-fluid flow and heat transfer problem. ...

... example under investigation is a square caster with size 0.2 × 0.2 × 0.4 m 3 , and a submerged entry nozzle with port outlet angle of 15 o downward. The computation region, as shown in Figure 1, represents just one quadrant of the casting steel system consisting of the strand region occupied by the steel and lubricant oil on the top, the mould region surrounding by mounted coil and the environment region. The finite element mesh with finer grid around the meniscus region, used in this study, consists of 16,478 tetrahedral elements with a total of 133,437 degrees of freedom. ...

Figure 10 gives the pattern of the mould oscillation and various instants of time for which the dynamic phenomena is to be presented. Figure 11 plots the velocity field on the symmetry plane at various instants of time during an oscillation cycle of the mould. ...
