Usage of Thermodynamic Activity for Optimization of Power Expenses in Respect of Casting Process in Arc Steel-Melting Furnace
Abstract
The equilibrium between carbon and oxygen has been investigated during oxidizing refining in an arc steel-melting furnace. It is shown that there is a possibility to apply an equilibrium thermodynamic. It has been established that during oxidizing refining FeO concentration in slag practically does not depend on C concentration in metal. It is demonstrated that in a number of cases metal carbon oxidation is characterized by the presence of a transit period that may be attributed to incomplete slag-formation process.
