| 摘 要： | 基于湍流模型与多相流模型的耦合,应用液面追踪技术(VOF),实现了对不锈钢板坯连铸结晶器内流体流动及钢/渣界面行为的模拟计算,并用水模拟结果进行了对比验证,在此基础上计算出实际的钢/渣界面特征及界面上钢/渣行为.通过分析水口的侧孔形状、出口倾角、水口浸入深度、结晶器宽度以及拉速对钢/渣界面特征及界面上钢/渣行为影响规律,指出了钢/渣界面行为与卷渣是密切相关的,进而探讨了钢/渣界面及卷渣形成的机理.

| Abstract: | Steel/slag interfacial behavior in a stainless steel slab continuous casting mold was numerically simulated on the base of a coupled model of turbulence and multiphase fluid flow and the VOF method.The results of numerical simulation were validated by a water model.The steel/slag interfacial profile and the behavior of steel and slag in the interface were obtained.By analyzing the influence of port form,port angle,SEN depth,mold width and casting speed on steel/slag interfacial behavior,it was pointed that ... |
