Simulation of Rotating Continuous Casting of Steel: Thermo-hydrodynamics and Particles Motion

Abstract : In Rotating Continuous Casting (RCC), the vertical billet, the mould and the support rolls rotate at about 1 rotation/sec. The mould is fed by a liquid steel free plunging jet. A numerical modelling of the RCC has been developed. The aim of this article is to study the effects of the free plunging jet and of the rotation on : the fluid flow, the thermal state, the solidification and on the particles motion. The modelling of the RCC uses a levelset method to capture the interface between the liquid steel and argon. A stabilized Navier-Stokes method is used to compute the fluid flow. A stabilized thermal solver is used to study the thermal field and the solidification of steel. A Euler-Lagrange approach is used to solve the motion of argon bubbles and inclusions. Hydrodynamics and particles motion are confronted to observations made on a cold water model. All developed methods are validated and applied to the RCC.
