| 摘 要： | 向钢包保护套管中吹入惰性气体,利用套管中湍急的注流,可将气体离散为弥散微小气泡.通过计算套管中注流的能量分散强度,得出了套管中弥散微小气泡的最大尺寸,并采用伯努利方程分析了套管中注流的压力分布.理论计算结果与文献报道及实验室水模实验结果一致.

| Abstract: | Highly turbulent flow in the shroud nozzle of a ladle can split introduced inert gas into fine bubbles, which enhances the removal of fine inclusions from molten steel. The maximum size of the bubbles was obtained through calculating the energy dissipation rate of liquid flow in the shroud. The pressure distribution of the fluid flow within shroud was analyzed with Bernoulli equation as well. The results by theoretic calculations are agreeable with these by water modeling experiment. |
