Influence Of Sulfur On Dissolution Of Graphite In Molten Iron

A clear understanding of iron carburization reaction occurring between molten iron and carbonaceous materials is of great importance in blast furnace, and it is one of the hot spots that ironmaking workers pay close attention to. Although carburization rates between iron and coke have been studied, the factors directly controlling it have not been clearly identified. This study focused on the kinetics analysis of iron carburization reaction. Sulfur content was determined as having positive influence on graphite carburizing reaction rate in the range of 0.02% - 0.06%. The values of apparent activation energy calculated by the experiment are consistent with the existing literature, which in turn proved the reliability of the experimental data.
