  • Publication number: 20220064064
    Abstract: In a method of processing molten material, in the form of non-metallic melt such as slag, into amorphous material, in which the molten material is vitrified by cooling, wherein the molten material for being vitrified is brought into contact with a metal bath and then discharged as amorphous material from the metal bath, the molten material is introduced into the metal bath via an open end of a dip tube immersing into the metal bath and is in the metal bath conveyed away from the area of the open end of the dip tube, preferably by means of a mechanical disintegrator, preferably a rotor.

  • Patent number: 11015869
    Abstract: A method for reducing molten raw materials, includes placing the raw materials, in a solid or molten state, on an inductively heated bed with coke pieces. The reduced melt that runs off the coke bed is collected and the waste gases are discharged. A coke bed is inwardly limited by a tube-shaped element through which the reaction gases are drawn off via a plurality of draw-off openings in the tube-shaped element. The corresponding device has a reactor for a bed with coke pieces and an induction heater with at least one induction coil. The reactor has a loading opening and a discharge opening for the treated melt. The coke bed is ring-shaped around a tube-shaped element. The material of the tube-shaped element allows inductive coupling to the induction field of the induction coil and it has draw-off openings for drawing off reaction gases from the coke bed.

  • Patent number: 9751762
    Abstract: A method for recycling organic waste material containing phosphorus oxides and metal oxides is particularly suited for recycling sewage sludge. The waste materials are mixed with chlorine carriers and then heat-treated at an air ratio of 0.85???1.6 and at least partially oxidized. The metal chlorides thus formed are drawn off and recovered and the fraction remaining after the metal chlorides have been drawn off is subjected to reduction in order to obtain elemental phosphorus.

  • Patent number: 9199109
    Abstract: In a method for processing used cathode material containing carbon, in particular used cathode troughs from aluminum production, the cathode material is put into a shaft furnace and, in order to gasify carbon, is subjected to a thermal treatment in the shaft furnace at a temperature above the ignition temperature of the carbon and above the evaporation temperature of toxic substances contained in the used cathode material. The reaction gases are conducted co-current with the carbon in a first longitudinal section of the shaft furnace and countercurrent to the carbon in a second longitudinal section of the shaft furnace. The reaction gases are drawn from a region of the shaft furnace having an enlarged cross-section between the longitudinal sections and are preferably subjected to an after-treatment.

  • Patent number: 8361187
    Abstract: A method for reducing oxidic slags and dusts possibly loaded with organics uses an inductively heatable coke bed extending in the axial direction and having a temperature gradient. Reaction gas is sucked off in an axial region of the coke bed between two induction bodies and metal regulus and slag melt are tapped on the lower end. An inductively heatable shaft furnace chargeable with a lumpy coke bed for the reduction of metallic slags is made of an electrically insulating refractory material, has an adjustable temperature gradient includes at least one cooled induction body on the head side, a suction connection in an axial region where the prevailing temperature exceeds the condensation point of the substances to be removed, located below the cooled induction body on the head side, and an opening for tapping metal regulus and slag melt is provided on the lower end of the furnace.
