    Abstract: A method of steelmaking in an at least partially refractory lined furnace. The process includes the steps of retaining a portion of a hot liquid slag from a previous heat, and altering the retained slag with basic slag forming material to increase its basicity, melting temperature, and viscosity, and to reduce its melting temperature below the melting point. The altering step is performed before charging ferrous materials for a new heat. Altered slag is then positioned on the bottom of the furnace, or on the furnace walls, or both, using a slag coating technique. Ferrous metal is then charged, after which a second charge of basic slag forming materials may be added prior to and/or during the first controllable oxygen blow. A slagging off step is conducted after less than one-half of the oxygen is introduced into the heat and when the mass of oxygen already introduced is sufficient to oxidize approximately all of the silicon introduced with hot liquid metal charged into the furnace.

    Abstract: A method for spheroidizing particles which have a relatively high softening temperature and/or a relatively large average diameter, including ceramic material having a diameter in excess of 0.45 mm. The method includes preheating raw material in a preheater to a temperature below an agglomeration temperature of the material, passing the preheated material in a plurality of streams through a first flame envelope, and cooling the spheroidized particles.

    Abstract: Furnace gas is aspirated through furnace gas conduits (44) to the low pressure throats (42) of the Venturi conduits (41) that move high oxygen content gas to the combustion chamber (28) of the aspirating burner (20). Fuel is injected through fuel conduit (46) to the combustion chamber (28) to mix with the gases and form the flame in the combustion chamber which is emitted at high velocity from the burner into the furnace.

    Abstract: A method and apparatus for improving the performance of a regenerative burner has a combustion chamber which receives and combusts controllable amounts of auxiliary fuel, an oxidizing gas, and possibly air to form hot combustion products. A controllable amount of a main fuel is then delivered to the combustion chamber and is pyrolyzed by the hot combustion products to produce a hot flame. By controlling the flame, one can maintain optimal temperature of the combustion air passing through the flame. Sensing means and computing means allow for automatic adjustments of fuel, oxygen and air flow to further maintain optimal combustion air temperatures.

    Abstract: A burner/injector for providing a localized impingement flame or multiple flames for scrap heating and melting through use of a fluid fuel and at least one oxygen rich oxidizing gas. The burner/injector includes a liquid-cooled combustor for generating an impinging flame directed toward a scrap pile and a structure for injecting a controllable amount of a solid carbonaceous fuel and a controllable flow of high velocity oxidizing gas into space that has been previously occupied by the impinging flame. The burner/injector may be equipped to inject a solid slag forming materials and/or slag deoxidizing materials, and/or to inject an additional oxidizing gas for burning a small portion of preheated scrap, post-combustion of CO and iron-carbon melt refining. The burner/injector may be arranged as a simple liquid-cooled combustor permanently mounted through the furnace wall or roof, and may be equipped with single or multiple channels for injection of solid material and high velocity oxidizing gas. Separate injecting lances for high velocity oxidizing gas and/or solid carbonaceous fuel may be mounted on the furnace. Both the lances and the combustors may be equipped with a nozzles for additional injection of the additional oxidizing gas.
