抑旋板条件下多流中间包流动特性的数值模拟
Numerical simulation of flow characteristics in multi - strand tundish under inhibiting baffle condition
摘要
Abstract
Effect of the inhibiting baffle on the flow field characteristics in tundish were studied by a numerical simulation based on a practical 35 ton symmetric four - strand tundish in a factory. The results showed that a counterclockwise vortex above the four strand can be easily caused while the inhibiting baffle is not applied, and the slag entrapment appears when the steel free surface reaches 69 mm. When the inhibiting baffle is installed near the four strand, the counterclockwise flow field is broken up, the flow velocity of the molten steel near the nozzle is slowed down, and stability of the liquid surface is improved, as a result, the sink vortex formation is obviously inhibited. By changing the angle and height of the inhibiting baffle, the molten steel can flow radially with no obvious vortex into the steel outlet, the slag entrapment critical height decreases by 40. 6%, the metal yields is increases significantly.关键词
