Calculation of Foam Behavior Parameters in Foaming Prosess Originated from Re-ducing Oxide by Carbon in Melten Slags

The mechanism of dynamics and heat transfer of reducing oxides by carbon in molten slags was analyzed and the relationship between the gas quantity of oxide reduction and time was determined. The foaming equations originated from the reaction were established. A software for calculating foam behavior parameters were introduced. Specially, the determination of the beginning time of rupture foam was discussed in detail. By means of the experimental results of reducing TiO₂ in an induction furnace (10 kg) in laboratory, the foam behavior parameters originated from the reaction in the molten slags were carried out through the software.
