Effect of Al Dross Addition on Temperature Improvements in Molten Steel by Blowing Dry Air

The CO2 emissions of electric arc furnaces (EAFs) can be reduced by decreasing the electrical energy consumed in melting iron scraps utilizing chemical energy. In general, efficiency EAF process improved using oxidation reaction heat and carbon combustion. When is added to molten steel, it not completely dissolved because its high point, floats slag layer, owing low density. Al dross a byproduct aluminum smelting, contains over 27 mass% metallic aluminum. As exothermic larger than that oxidation, useful source process. this study, utilize mixtures cokes as sources process, we investigated dissolution concentrations, ratios, rate constants steel. improvement steel temperature was blowing dry air into melt after dross.
