| 摘 要： | 为深入了解RH-PTB真空精炼过程的循环流量及混合特性,建立了与RH装置原型的比例为1∶5.5的水模型,考察了不同工艺参数对RH-PTB循环流量及均混时间的影响.结果表明,随着气泡行程的增大、真空室内液面高度的增大及钢水处理量的减小,循环流量增大,均混时间缩短.因此在实际生产中,当钢水处理量过大时应采取措施增大循环流量.对实验数据进行回归处理得到了循环流量、均混时间的表达式.

| Abstract: | To have an insight into the circulating flowrate and mixing characteristics in RH-PTB vacuum refining process, the relevant system was modeled on a scale of 1:5.5 to investigate the effects of different parameters on the circulating flowrate and mixing time. The results showed that with the increasing bubbles' travel and the liquid level in vacuum chamber and decreasing quantity of liquid steel for refining, the circulating flowrate increases while the mixing time decreases. So, some effective measures should be taken in actual system to increase the circulating flowrate in case the quantity of liquid steel for refining is overmuch for refining. Besides, the expressions of circulating flowrate and mixing time were derived by regression equation with experimental data. |
