| 摘 要： | 基于流体力学基本原理,采用Fluent软件建立板坯连铸结晶器及浸入式水口的三维有限元体积模型,模拟研究了水口不对中和水口单孔结瘤条件下结晶器内流体的流动特征和温度场分布状况.结果表明:水口对中不良时,结晶器两侧回流明显不对称,液面会产生旋涡,水口偏向侧温度高于水口偏离侧;水口出口单孔结瘤时,未结瘤侧流股增强,液面流速增大,并且液面有涡流产生,结瘤侧新鲜钢液减少,温度偏低.

| Abstract: | Based on the basic principle of fluid mechanics,three-dimensional finite volume models of a slab continuous casting mold and a submerged entry nozzle(SEN) were established by Fluent software.When the nozzle was off-center and clogging, the flow characteristics of fluid and temperature field distribution in the mold were investigated.The results showed that while the nozzle was off-center,circulation flows in both sides of the mold were asymmetric and there were vortexes in the free surface.The temperature i... |
