液体流动，热转移和在模子的钢的团结那么复杂却关键，决定连续的扔平板的表面质量。在当前的学习， 2D 数字模型被流畅的软件建立在模子模仿液体流动，热转移和钢的团结。VOF 模型和 k- 模型被使用模仿三个阶段(钢，炉渣和空气) 的流动地，并且团结模型被用来模仿团结过程。在新月的现象也通过在液体钢和炉渣以及模子摆动之间的界面的紧张被探索。模型包括了 20 公里澄清热转移和模子的温度分发的厚模子。模拟结果证明液体钢在模子作为上面的逆流和更低的逆流流动，并且小发行量在新月形成。液体炉渣在新月流动离开角落或渗透到在模子和壳之间的差距，模子在否定长带阶段或在积极长带阶段震荡。模仿的沥青和摆动标记的深度在平板上接近到理论沥青和测量深度。

英文摘要：

Fluid flow, heat transfer and solidification of steel in the mold are so complex but crucial, determining the surface quality of the continuous casting slab. In the current study, a 2D numerical model was established by Fluent software to simulate the fluid flow, heat transfer and solidification of the steel in the mold. The VOF model and k-ε model were applied to simulate the flow field of the three phases（steel, slag and air）, and solidification model was used to simulate the solidification process. The phenomena at the meniscus were also explored through interfacial tension between the liquid steel and slag as well as the mold oscillation. The model included a 20 mm thick mold to clarify the heat transfer and the temperature distribution of the mold. The simulation results show that the liquid steel flows as upper backflow and lower backflow in the mold, and that a small circulation forms at the meniscus. The liquid slag flows away from the corner at the meniscus or infiltrates into the gap between the mold and the shell with the mold oscillating at the negative strip stage or at the positive strip stage. The simulated pitch and the depth of oscillation marks approximate to the theoretical pitch and measured depth on the slab.
