| Abstract: | The mechanism of silicon transfer in a blast furnace has been studied. It is concluded that the contribution of slag-metal
reaction to silicon increase in the metal will not be very important because of the slow rate of the reaction and high oxygen
potential of slag in a blast furnace. By making use of kinetic and thermodynamic data, it is shown that the reaction of SiO
containing gas with liquid iron of high carbon content takes an important role in the silicon transfer in a blast furnace. |
