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.

Abstract: The invention relates to a porous granulated steel slag having a weight per unit volume of less than 1 kg/dm.sup.3 in the loosely dumped state and of 0.99 kg/dm.sup.3 in the compacted dumped state, having a free calcium oxide content of at most 1/10 of the content in the non-granulated slag. The present steel slags are obtained by spraying a molten stream of steel slag with a sprayed pressurized stream of water. After comminuting, for example by grinding, and removal of iron, the porous granulated steel slag can be separated into a ferrite-richer fraction, which can serve as raw material for steel production, and a lower-ferrite fraction, which can serve as raw material for an inorganic binder. Granulated steel slag is also used as aggregate in building materials, as raw material in road building materials and for embankment materials, and as cement replacement material.

Abstract: A furnace 10 for smelting iron ore and/or refining molten iron 20 is equipped with an overhead pneumatic lance 40, through which a center stream of particulate coal 53 is ejected at high velocity into a slag layer 30. An annular stream of nitrogen or argon 51 enshrouds the coal stream. Oxygen 52 is simultaneously ejected in an annular stream encircling the inert gas stream 51. The interposition of the inert gas stream between the coal and oxygen streams prevents the volatile matter in the coal from combusting before it reaches the slag layer. Heat of combustion is thus more efficiently delivered to the slag, where it is needed to sustain the desired reactions occurring there. A second stream of lower velocity oxygen can be delivered through an outermost annulus 84 to react with carbon monoxide gas rising from slag layer 30, thereby adding still more heat to the furnace.

Abstract: The service life of permeable refractory elements is improved by conserving in a vessel a fluid slag formed during refining of a charge after a liquid metal has been cast by tipping the vessel, depositing and spreading the slag over the bottom by bringing the vessel back to its upright position, and leaving the slag to harden and set on the bottom, while a sufficient pressure is maintained in the permeable refractory elements to ensure a permanent flow of a stirring fluid.

Abstract: A method for continuously measuring slag foaming within a converter during blowing and an apparatus for practising the method are disclosed.In this method, the foaming slag level is determined by detecting and processing a beat signal developed between the frequency-modulated transmitted wave and the reflected wave of a microwave radar. The apparatus for practising this method comprises a microwave generator, an antenna and a waveguide, and signal processing circuitry. The microwave generator generates frequency-modulated microwaves and supplies them to the antenna which is provided with a waveguide for directing these microwaves into the converter. The antenna with the waveguide are provided with water-cooling means and air purge means to overcome the heat, dust and splash from the converter. The signal processor determines the foaming slag level by detecting and processing the beat signal between the microwaves reflected from the slag within the converter and the reflected waves from a reference reflector added to the antenna.
