Abstract
As one of a series of experimental studies designed to establish the mechanism of Si transfer in the blast furnace, carburization of iron and iron-sulfur melts by CO gas has been carried out in the temperature range from 1570 to 1720°C.
It was observed that the rate of carburization becomes larger as the temperature lower.
The mechanism of carbon transfer has been proposed and the adsorption phenomena, an apparent activation energy for the reaction 2CO (g)→C+CO2 (g), and the effect of mass transfer in gas-liquid boundary layer have been considered both experimentally and theoretically. From this study, it is concluded that the carbon transfer from gas phase to molten iron may have minor contribution to the carburization in the blast furnace.
