Effect of TiO₂ Content on the Foaming Process Originated from Reducing Fe₂O₃ in the Synthetic Slag

The foaming processes originated from reducing TiO₂ and Fe₂O₃ by carbon in the synthetic slag were investigated under different conditions in laboratroy. The formation and rupture coefficients, average foam life, foam intensity and beginning time of the rupture foaming process were determined by means of experimental results. The influence of temperature, TiO₂ added in synthetic slag and TiC content in original slag on these foaming processes were discussed through the foaming parameters. It is found that the secondary foaming phenomena in twice can take place when the original slag contains when more TiC land more TiOz is added.
