Kinetic experiments have been made on
C oxidation between Fe
tO containing slag and molten iron of high
C concentration ([%C])≅4.4) at 1300°C under mechanical stirring conditions. Effects of
Si and
P in the metal and P in the slag on the
C oxidation reaction rate have been examined, as well as effect of mechanical stirring on the reaction rate.
The
C oxidation rate is considerably reduced by slight increase in P concentration in the slag. It is also found the
P in the metal has no significant effect on the
C oxidation rate. The
C oxidation rate decreases with increasing
Si concentration in the metal. A mathematical model is proposed to explain the simultaneous reactions in this slag-metal system.
