Abstract
In the continuous steel casting process, argon, as a gas neutral to liquid steel, is used as a protective gas or medium developing the pattern of liquid steel and non‐metallic inclusions motion. With the appropriate argon flow rate, the hydrodynamic structure of liquid steel motion can be effectively modified in the tundish. The facility under investigation is a single‐nozzle slab tundish. Two unique argon injection barrier have been designed, whose purpose is to stimulate the motion of liquid steel within the working space of the tundish. Computer simulations of the liquid steel flow and argon behavior were done using the Ansys‐Fluent computer program. For the validation of the numerical model and verification of the correctness of the computer simulation results, a glass water model was used. It has been found that the use of the gas‐permeable barrier with two porous plugs in the tundish effectively influences the pattern of liquid steel flow.
