METHODE OF FEO PREDICTION FOR MOLTEN SLAG IN ELECTRIC ARC FURNACE

摘要

The present invention relates to a method to predict an iron oxide content among molten slag in an electric furnace and, more specifically, to a method to predict an iron oxide content among molten slag in an electric furnace capable of controlling a predict of an iron oxide content in an electric furnace. According to an embodiment of the present invention, provided is the method to predict an iron oxide content among molten slag in an electric furnace comprising: a step of measuring a molten steel temperature T (C) and a carbon content C (%) of molten slag before tapping into the electric furnace; and a step of predicting an iron oxide content among molten slag through the following relation using the carbon content and molten steel temperature. (Relation) Iron oxide content (wt%)=231-(0.129T)-(0.702C)
