| Abstract: | The application of Al CaO as heating agent to heat molten steel is studied with a medium frequency induction furnace. The factors on heating efficiency are analyzed in the experiments. The heating efficiency of aluminum can reach 87 percent in steel production. The subsidiary functions of Al CaO are also studied in connection with the chemical composition change of molten steel during heating. The results show that heating molten steel is feasible with Al CaO as heating agent. Al CaO possesses the ability of desulphurization while heating steel.And it will be an efficacious heating agent against scabbing at the tundish nozzle in continuous casting. |
