建立了盛钢桶到中间罐钢液吸气的物理模型,利用NaOH水溶液 CO2系模型来研究注流及中间罐液面的吸气(CO2)速率,从而考察操作参数对中间罐钢液吸气速率的影响。结果表明:氧分压、注流半径增加时,熔池内钢液的吸气速率提高;注流速度增加时,中间罐液面的吸气速率提高;另外,中间罐结构对中间罐液面吸气速率也有影响。
The physical model of aspiration from the ladle to the intermediate tank was established. The CO2 gas flow rate in the injection and the intermediate tank was studied by using the CO2-based model of NaOH aqueous solution to investigate the effect of operating parameters on the intake of liquid steel Effect of rate. The results show that when the oxygen partial pressure and the injection radius increase, the suction rate of molten steel in the molten pool increases. When the injection velocity increases, the suction rate of the liquid in the intermediate tank rises. In addition, The gas velocity is also affected.
