Moving through the liquid steel, argon bubbles intensify the chemical and thermal homogenisation processes and liquid metal refining. The present study reports the physical and mathematical modeling of bubbles behaviour in the tundish with argon injection system. The 210 litre–capacity one strand slab tundish model was made on a scale of 2:5. The laboratory water model experiments have demonstrated that the identical porous material used in gas-permeable barrier may generate gas bubbles varying in size and shape. This fact will also affect both vertical and horizontal velocities attained by the bubbles. From numerical simulations influence of argon flow rate on liquid steel velocity for free surface in the tundish was obtained. The results from numerical simulations indicate that argon create increasing of liquid steel velocity and vortex structures.
Key words: tundish / physical modeling / numerical simulation / gas permeable barrier / bubbles behaviour
