以某厂210t钢包RH精炼装置为研究对象,通过1∶4水力模型对现场生产过程进行物理模拟,研究驱动气体流量、钢液处理量、浸入深度、真空度和气孔数对循环流量的影响。研究结果表明：RH循环流量随着驱动气体流量、浸入深度、真空度、气孔数的增大和处理量的减小而增大;该RH装置的循环流量最大可以达到66.4%。
To study the production process of 210 tons RH in a steelmaking plant,a water model with a scale of 1∶4 is established in the lab.The investigations are aimed to ascertain the effects of driving gas flow,molten steel treatment capacity,immersion depth,vacuum degree and the number of stomata on the circular flow in the RH device.The results showed that the circular flow increased with the decrease of driving gas flow,immersion depth,vacuum degree and the decrease of molten steel treatment capacity.The circulation flow can reach a maximum value of 66.4 %.
