Based on a water model with the size of one fifth of the real CAS ladle,the improvement of the mixing effect in CAS-OB process using double-nozzles bottom blowing technology was researched by analyzing the flow field and determining the mixing time.Results show that double-nozzles bottom blowing technology could greatly reduce the mixing time,also could change the flow field in the low-intensity stirring area of ladle and improve the mixing effect in the middle and lower part of ladle.The experimental formula for expressing the effect of bottom blowing flow rate Q and depth of inserting snorkel H on mixing time $\frac{\tau-\tau_0}{\tau_0}=0.59 Q^{-0.74}\left(\frac{H}{H_L}\right)^{0.52}$ is obtained by free factors analysis.
