The application of Al-CaO as compound heating agent to heat molten steel in medium frequency induction furnace wads studied. Factors on heating efficiency were analyzed in the experiments. The heating efficiency of aluminum can reach 87 percent in steelmaking. The subsidiary functions of Al-CaO were also studied in connection with chemical composition change of molten steel during heating. Heating molten steel is feasible with Al-CaO as compound heating agent. Al-CaO has the ability of desulphurization while heating steel. The application may be efficacious against the tundish nozzle blockage during the continuous casting.
