Abstract

Synopsis: A study has been made on the desulfurization by the use of CaO-CaF ₂ flux and CaO-Na ₂ CO ₃ flux with mechanical stirring. The followings were found: 1) The desulfurization rate was correlated with the mixing ratios of CaF ₂ and Na ₂ CO ₃ in the fluxes and had local maximum. 2) Although aggregation of flux was observed in the case of the high mixing ratio of CaF ₂ , the reaction area seemed to be constant throughout the reaction. This is because aggregation was almost completed at the very beginning of the experimental time. 3) It is possible to estimate the rate of desulfurization by using effective liquid phase ratio, in which the liquid phase used as cross-linking agent is excluded from the total liquid phase ratio.
