| Research Abstract |
In the conventional iron making process, impurities in iron ore such as phosphorous are reduced and existed in iron phase due to excessively low oxygen partial pressure at the hearth of blast furnace. Low impurity iron might be directory obtained by using gas reductant because Oxygen partial pressure can be controlled, i.e. “Direct Steel Making". In this condition, solid iron is obtained due to not carbon saturated condition. In this study, equilibrium distribution of impurities between solid iron and molten oxide was measured experimentally at 1350℃.
