Abstract

In the current study, a mathematical model was established to investigate meniscus solidification and slag infiltration in the mold. The model considered the two-dimensional steel-slag-air three-phase fluid flow, heat transfer, solidification of the steel and mold oscillation. The calculated solidification shell was compared with measured hook lines to validate the model. The initial solidification and slag infiltration at the meniscus were revealed during an oscillation cycle. The influence of casting parameters on initial solidification was studied. Through simulations, the liquid slag flowed into the gap between the steel shell and copper plate during the positive strip stage, while it flowed out of the gap during the negative strip stage. The solidification depth of the meniscus from the solidification tip to the inner mold face reduced with the increase of casting temperature and casting speed and the decrease of water flow rate in the mold and oscillation amplitude.
