With established argon bottom blown ladle three dimensional non-stable three-phase flow math model

Fluent software and Simple calculation method the shield slag flow characteristics during ladle refining process in bottom argon blown are studied and the effect of gas flow rate 200-3500 L/min of nozzle with diameter 0.1 m on slag eye size and slag layer flow behavior is analyzed. Results show that with increasing gas flow rate the slag eye enlarges and as argon flow rate is 400-2000 L/min the slag eye size and distribution of flow field in ladle are reasonable and available to refine； with increasing thickness of slag layer the slag eye range decreases but as the thickness of slag layer is more than 200 mm

the effect of thickness of slag layer on slag eye size is not obvious.
