In order to enhance the stirring effect of 180 t ladle bottom blowing argon on molten steel in a steel plant
a mathematical model of bottom blowing argon process is established according to the design parameters of the model. The flow field characteristics of ladle bottom blowing argon process are mathematically simulated by using CFD software fluent. Based on theory of fluid mechanics
the effects of center distance 1/3R
1/2R and 2/3R and 300-1000 L/min blowing argon flow rate on the velocity flow field
proportion of "dead zone"
as well as mixing time in the ladle are calculated and analyzed. The results indicate that during process of the bottom blowing argon
when the center distance between the permeable brick and bottom center of the ladle is set as 1/2R and the blowing argon flow rate is 600 L/min
the stirring effect is best with mixing time 195 s.
