The mixing time of steel in a 130t ladle with single nozzle blowing
double nozzle blowing in right angle location and symmetry location with different gas rate was measured by established water model using conductivity method. Results showed that the mixing time with double nozzle blowing was shorter than that with single nozzle blowing and stirring effect was better than that of single nozzle blowing. As nozzle location distance from center of ladle bottom for single nozzle blowing was 0.55R(ladle bottom radius)
the mixing time was shortest; and as distance between double nozzle for double nozzle blowing increased from 0.40R to 0.70R
