Abstract

Aiming at the problem that the existence of inclusions in the tundish continuous casting process can easily lead to quality defects of the slab, the stainless steel continuous casting tundish was taken as the research object. The effects of flow control device, inclusion density and inclusion size on the mixing characteristics of molten steel and inclusion behavior in tundish were studied. The results showed that compared with the tundish without flow control device, the average residence time of molten steel was prolonged by about 49 s, the dead zone volume fraction was reduced by 8.93%, and the piston fluid integral rate was increased by 12.68%. In the turbulence inhibitor (TI) tundish with weir–dam combination, the removal rate of inclusions with a density of 2700 kg m−3 and a particle size of 5 μm is 63.32%, while the removal rate of large inclusions with a density of 150 μm could reach 89.04%. When the inclusion particle size was 10–50 μm and the density was 2700–4500 kg m−3, the effect of inclusion density on inclusion removal rate was small. At the same time, when weir–dam combination TI tundish was set, the inclusions were mainly limited to the slag–metal interface of the first and second chambers of the tundish. The removal rate of inclusions in the first chamber was generally improved, with 10 μm inclusions accounting for 47.67% and 150 μm inclusions accounting for 60.69%. Furthermore, it has the best effect on the removal of small-size inclusions, especially those less than 70 μm.
