2 slab caster of Meishan Steel,the influence of casting speed,immersion depth of nozzle and blowing argon flowrate on bubble distribution in the mold was investigated by using water model.

The interfacial behavior between fluid steel and molten slag layer in a slab continuous casting mold with blowing argon gas was described using the VOF (volume of fluid) method and Lagrange multi-phase flow model,and the prediction was validated by the water model.

By adopting the measures such as discharging at high temperature, blowing argon and stewing treatment, the inclusion in high carbon Si-Mn cast steel can reduce obviously, its content can be controlled under 0.

Study on inclusion removal of ladle argon blowing process;

Numerical simulation of argon blowing behaviors of molten steel with purging plug in ladle bottom;

Mathematical simulation of flow field of molten steel in ladle furnace with argon blowing;

Influence of argon injection into slab continuous casting molds on slag entrapment in billets;

1 continuous slab-casting machine in Baosteel as the object, a multi-phase model was applied to simulate the velocity, temperature fields and gas distribution of molten steel with argon injection.

Through degassing by argon injection into ladle,however,We have improved the quality of steel and satisfied the performance needs of steel products.
