The temperature of molten steel in a ladle is raised to a predetermined level by introducing a plurality of oxygen containing gas streams beneath the surface of molten steel and introducing a predetermined quantity of an oxidizable fuel, such as aluminum or silicon, into the molten steel.
Claims7
A method of heating molten steel contained in an open top refractory lined ladle comprising introducing a plurality of oxygen containing gas streams beneath the surface of the molten steel to an unconfined reaction zone spaced a substantial distance from the refractory lining and introducing a quantity of an oxidizable noncarbonaceous fuel into the reaction zone sufficient so that the oxidation thereof by the oxygen containing gas steams raises the temperature of the molten steel to a predetermined level.
