Abstract

In order to solve the problem of low inclusion removal rate in the process of micro-porous argon blowing in tundish, the effects of micro-porous argon blowing position in tundish, porosity of porous brick and bubble size on inclusion removal were studied by numerical simulation. The simulation results show that the porous brick with porosity of 10% are installed downstream of the tundish inlet dam. When the blown bubble size is controlled to 2 μm, the removal rate of 20 μm micro inclusions in tundish reaches the highest 37%, which can effectively improve the purity of molten steel.
