Abstract
A coupled model of continuous casting with mold oscillation was established including multiphase flow, heat transfer and solidification. The process of initial solidification and the formation of oscillation marks were analyzed. The accuracy of the model was verified by comparing the depth of oscillation marks and slag consumption with the measurement by the plant. The main results showed that during the negative strip stage, part of the slag near the initial solidified shell affected by the downward movement of the slag rim was squeezed out from the slag channel to the slag pool, meanwhile pressure difference of shell and heat flux was maximized, shell grew rapidly. The oscillation marks were formed during the negative strip stage. The effect of interfacial tension on the oscillating marks formation was quantitatively analyzed. These results provide theoretical support to improve the quality of the slabs.
