Applied Research on Electrical Conductivity of Slag in Metallurgical Reaction
Taking the deoxidization using solid electrolyte as an example, the electrochemical reaction mechanism between metal and slag was briefly introduced. The decarburizations of molten iron by CaO-SiO2-Al2O3-FeOx slag were studied through connecting metal and slag by electronic conductor and applying static electric field on the metal-slag respectively. The experimental results indicated that the electrical conductivity of slag play an important role in the electrochemical reaction between metal and slag, and any methods beneficial to the transfer of electron and/or hole between metal and slag can increase the reaction rate. The mobility of oxygen ion in slag was limited by the transfer of electron between metal and slag, so the existence of electronic conductor between metal and slag provided a shortcut for the transfer of electron and consequently increased the mobility rate of oxygen ion. Therefore, any methods that increase the transfer rate of electron between metal and slag can improve the mobility of oxygen ion in slag.
