摘要
用顶吹 CO2 - Na OH溶液体系模拟了 RH- KTB顶吹氧溶氧过程。通过对碱液吸收 CO2 反应动力学的研究 ,考察了操作参数对 RH- KTB顶吹氧脱碳过程中溶氧反应的影响。结果表明 :提高气相中氧分压、增加提升氩气流量或采用低枪位喷吹都有利于加速溶氧脱碳。实验中还发现 :顶吹氧气流量对容积传质系数影响很小 。
The top injection of oxygen gas in RH KTB degasser has been simulated by the top injection of CO 2 in a physical model with NaOH solution. The effects of operation parameters on oxygen absorption of molten steel in RH KTB degasser with top oxygen injection were analyzed through the kinetics study of NaOH solution absorbing CO 2. The results showed that high oxygen partial pressure in the vacuum vessel, large flow rate of argon gas and low position of top oxygen injecting lance will accelerate the decarburization in RH KTB reactor. It is also found that the oxygen gas flow rate has little effect on the volume mass coefficient of liquid phase.
