摘要： A method of production of Zinc dust, which includes melting Zinc products in a melting furnace on a semi-continuous basis, transferring at least a part of the molten Zinc products to a vaporizing furnace, vaporizing the molten Zinc in the vaporizing furnace into Zinc vapour on a substantially continuous basis, transferring Zinc vapour from the vaporizing furnace to a condenser, and condensing the Zinc vapour to form Zinc dust which includes circulating the zinc vapour in the condenser and through a cyclone cooler. A zinc dust production plant includes a vertical crucible melting furnace (12), a vertical crucible vaporizing furnace (14) and a condenser (18) in fluid communication with the vaporizing furnace, with a heat exchanger in the form of a vapour circulation system (58).

摘要： An apparatus for condensing metal vapors has at least one inlet conduit that is cooled to cause a portion of the metal vapor to condense to liquid. The apparatus also has a holding tank that is connected to the inlet conduit that collects condensed liquid metal. The apparatus also has at least one outlet conduit connected to the holding tank that is cooled to cause a portion of the remaining metal vapor to condense to solid metal. The apparatus also has at least one heater that heats the at least one outlet conduit to cause the solid metal to melt to liquid metal and subsequently flow in to the holding tank. The apparatus also has at least one sealing mechanism located at a distal end of the at least one outlet conduit for preventing metal vapor and carrier gas from exiting the outlet conduit during heating of the outlet conduit.

摘要： A process for extraction of zinc from a material containing one or more iron oxides and zinc oxide includes heating a composite body of the material and a carbonaceous material in a reduction zone. The reduction zone contains a reducing atmosphere at a temperature insufficient to effect melting of the iron in the material but at a temperature and for a time sufficient to form a reductant from the carbonaceous material and to reduce a predetermined amount of the zinc oxide to zinc vapour. The process also includes collecting the zinc vapour and cooling it to form liquefied or solid zinc.

摘要： Presented is a method and apparatus for treating an exhaust gas. A series of filters and conditioning units are used to separate and extract various substances from the exhaust gas, typically originating from an industrial process. In an exemplary embodiment, a cyclone filter, a ceramic filter, a baghouse filter, and a pair of gas conditioners are used to initially separate and extract iron-rich dust from an exhaust gas and then extract zinc from the gas.

摘要： Liquid metal is continuously recovered by condensing metal vapour in a sealed system, more or less at atmospheric pressure, and collecting liquid metal in a crucible. The contents of the crucible are agitated and the temperature is controlled to prevent the liquid metal from solidifying. Liquid metal and dross are tapped from the crucible.

摘要： A method of producing a nickel base alloy includes casting the alloy within a casting mold and subsequently annealing and overaging the ingot at least 1200 °F (649 °C) for at least 10 hours. The ingot is electroslag remelted at a melt rate of at least 8 Ibs/min. (3.63 kg/min.), and the ESR ingot is then transferred to a heating furnace within 4 hours of complete solidification and is subjected to a novel post-ESR heat treatment. A suitable VAR electrode is provided form The ESR ingot, and the electrode is vacuum arc remelted at a melt rate of 8 to 11 lbs/minute (3.63 to 5.00 kg/minute) to provide a VAR ingot. The method allows premium quality VAR ingots having diameters greater than 30 inches (762 mm) to be prepared from Alloy 718 and other nickel base superalloys subject to significant segregation on casting.
