  • Patent number: 8617457
    Abstract: 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.

  • Patent number: 7648558
    Abstract: Methods for treating aluminum in a furnace. An aluminum charge is introduced into a furnace and melted with heat from at least one burner. The burner is supplied with at least one oxidizer and at least one fuel. The oxidizer is made up of at least 10% oxygen by volume. The concentration of a first gas is measured in the furnace atmosphere or in a flue gas exiting the furnace. The oxidation of the molten aluminum is then reduced by holding the flow rate of the oxidizer steady while varying the flow rate of the fuel, according to the concentration of a second gas in the furnace or in the flue gas exiting the furnace. The concentration of the second gas is determined by comparing the measured species concentration and the intrinsic concentration which would be present absent the aluminum charge.

  • Patent number: 6478846
    Abstract: The invention relates to a method for injecting reducing agents into a shaft furnace in which the reducing agent is transported within a pneumatic delivery stream to the shaft furnace according to the flowing steps; a) dividing the delivery stream into a number of partial streams, b) transferring the individual partial streams through a heating unit, and c) heating the reducing agent within the individual partial streams inside of the heating device. A device for carrying out the inventive method comprises, for example, a delivery line in order to pneumatically deliver the reducing agent to the shaft furnace, and a number of heat exchange pipes which are integrated in the delivery line using a parallel connection, said connection relating to flow techniques, such that the pneumatic delivery stream is divided into a number of partial streams. The inventive device also comprises a heating unit for transmitting heat energy to the individual partial streams.

  • Publication number: 20020162417
    Abstract: A process for producing purified cobalt from a mixture comprising metallic species of cobalt and metallic species of at least one of the group consisting of nickel and iron, comprising producing a metal carbonyl mixture of cobalt carbonyl and at least one of nickel carbonyl and iron carbonyl from the metallic species mixture; separating the nickel carbonyl and/or iron carbonyl from the cobalt carbonyl; treating the cobalt carbonyl with an effective amount of a complexing gaseous mixture of nitric oxide/carbon monoxide to produce cobalt nitrosyl tricarbonyl; and decomposing the purified cobalt nitrosyl carbonyl to provide purified cobalt and regenerated complexing gaseous mixture for recycle. The process provides cobalt of improved quality in an optionally, continuous and closed-loop manner. Preferred processes include either aqueous and/or gaseous process steps.

  • Patent number: 6245122
    Abstract: An apparatus and method for reclaiming contaminated scrap metal, more particularly an improved reverberatory furnace designed for melting scrap. The amount of hydrocarbons volatilized from the melting of contaminated scrap is measured and the fumes are passed into the main hearth for burning. As the amount of fuel value contained within the fumes increases, the amount of fuel provided to the burner is proportionally reduced while the amount of oxygen is kept constant. This will ensure that the amount of fuel and the amount of oxygen present within the furnace is completely burned without excessive free oxygen or unburned fuel building up within the furnace or furnace exhaust. The burner will be operating under lean fuel conditions or under fuel rich conditions such that the flame temperature is lower than at stoichiometric firing, whereby the burners create reduced NOx.

  • Patent number: 4643402
    Abstract: The invention provides a method and apparatus for producing a regulated atmosphere in a heat treating furnace. In the preferred embodiment, liquid methanol is heated sufficiently to cause it to dissociate into hydrogen and carbon monoxide, i.e. the combustible components. These dissociated combustible components are then mixed with a relatively inert gas such as nitrogen. This mixture of combustibles and non-combustibles forms the atmosphere for the furnace. The proportion of one or more combustibles in the mixture is measured, and the flow of the inert gas into the mixer is regulated so as to maintain precisely the desired ratio of combustibles to non-combustibles in the furnace atmosphere. The invention includes various mechanisms for preventing unsafe temperature and pressure conditions, and for insuring that unwanted byproducts of dissociated methanol are not created.

  • Patent number: 4436289
    Abstract: An automatic control for a multi-zone push type carburizing furnace capable of controlling the flow of either an endothermic gas atmosphere or a nitrogen methanol atmosphere at both high and low flow rates and during normal and suspend carburizing utilizes cascaded multi-stage valving to assure good separation of the atmospheres in adjacent zones. The first stage of the cascaded multi-stage valving controls the total gas flow, and the second stage routes the gas to individual zones of the furnace.

  • Patent number: 4395021
    Abstract: A vertical continuous annealing furnace has two furnace covers vertically spaced away from each other. Each furnace cover is laterally slidable with respect to the furnace proper and has two long narrow openings through which strip is passed. There is a relatively small pre-chamber between the first furnace cover above and the second furnace cover below. The space below the second furnace cover constitutes a heating chamber. A partition extends from the undersurface of the second furnace cover to near the bottom of the furnace, dividing the heating chamber into a heating zone and a soaking zone. In charging and discharging the strip, the two furnace covers are alternately opened and closed, thereby keeping the heating chamber out of exposure to the outside air.
