Numerical Simulation of Fiuid Field of Molten Steel in the Mold on 700mm×700mm Billet Continuous Caster

Abstract:

The fluid flow of Q235 molten steel in 700mm×700mm billet mold has been numerically simulated by a software FLUENT. By comparing the influence of submerged entry nozzle with different immersed depths, different number of holes and different opening angles on the distribution of fluid field, the structure of mold and the involved process parameters are optimized. With the application of the optimized structure and process parameters, the stability of fluid field is increased and the thickness uniformity of steel shell is improved, so that the quality of continuous casting billet is ameliorated, which provides a theoretical basis for engineering application.
