抄録

Experiments were conducted on the hot metal treatment by adding CaO-MnO-CaF<SUB>2</SUB> flux to 2kg carbon-saturated iron at 1350°C.<BR>(1) By adding CaO-MnO-CaF<SUB>2</SUB> flux, desiliconization, desulfurization and [Mn] increase of carbon-saturated iron occurred simultaneously.<BR>(2) From the equilibrium oxygen partial pressure determined by [Si]-(SiO<SUB>2</SUB>) and that by [Mn] (MnO), the reaction: [Si]+2 (MnO)=2[Mn]+(SiO<SUB>2</SUB>) is considered to have almost reached equilibrium state.<BR>(3) By comparing Ls (=(%S)/[%S]) observed and that calculated using the numerical values of the sulfide capacity of CaO-SiO<SUB>2</SUB>-CaF<SUB>2</SUB> slag and the equilibrium oxygen partial pressure, desulfurization is also considered to be in equilibrium state.
