Abstract: (4833 Views)
In the process of steel continuous casting, tundish as an intermediate compartment between the cauldron and mold has an important role in inclusion removal and the turbulence reduction process before entering the mold. Basically, the cleanliness of molten steel entering the mold is effected by the type of tundish flow pattern and the it’s behaviore in the flotation and removal of non-metallic impurities.Therefore, suitable flow pattern and increase of inclusion residence time in tundish improve the process of inclusion removal and lead to get clean steel. In this research, by manufacturing of the glass tundish in 1:4 scale to do flow physical modeling, the effect of melt height on the flow behavior in single tundish was studied, by implementing of dam in tundish then, its performance in inclusion removal is compared. Independent variables in this study are as the diameter of the inclusions and different water levels in the tundish and the dependent variables are as the separation rate of inclusions from the melt and inclusions residence time in the tundish. By increasing the water height in tundish, the inclusion removal and residence time get reduce. In addition, by using the dam near inlet nozzle the flow pattern gets improved and the inclusion removal will be as slag.
