摘要： The invention relates to a method for the salt-free, non-oxidizing remelting of aluminum, the alloys thereof and aluminum scrap metals comprising possible impurities, such as inflammable oily substances, adhering inflammable or non-flammable materials and those substances that have a higher specific weight, in a rotating drum that comprises a combustion chamber, two feed valves and a burner nozzle. Natural gas or fuel oil are provided in a manner known per se as the source of energy and the oxygen is fed to the combustion chamber together with air via a feed valve. An electronic control adjusts the amount of air in such a manner that the oxygen quantity supplied together with the air corresponds exactly to the stoichiometric proportion required for the combustion of the source of energy supplied through the burner nozzle.

摘要： A metal melting closed furnace which includes a main chamber, a circulation wall connected to the main chamber by a communications passageway and a vortex well having a exit outlet for molten metal into the main chamber. A cover is emplaced over the vortex well. An inert gas bubble activated molten metal pump is provided in which there is an entry port in the circulation well and exit port tangentially arranged with respect to the periphery of the cavity. This exit port will typically be at or near the top of the vortex well. In order to reduce oxidation, inert gas bubbles are captured from this molten metal pump and are transported to an inert gas atmosphere or blanket above the molten metal vortex.

摘要： A metal-inorganic particle composite material 1 is heated into a melt 2. Flux 3 is thrown into the melt 2, and both the melt 2 and the flux 3 are brought into contact with each other sufficiently. The resulting melt 2 is then left at rest so as to be separated into an upper layer containing inorganic particles 2a and a lower layer composed of metal 2b. Subsequently the upper layer and the lower layer are recovered individually.

摘要： A continuous process is provided for rapid melting of a variety of virgin and recycled ferrous and non-ferrous metals. This is accomplished by distributing the introduction of the unmelted charge materials and hence the melting heat requirements along an elongate gas-solid-liquid reaction zone within a rotary furnace, according to the distribution of heat available to effect melting. In the case of fine-sized metal charge materials, fluxes and additive reagents, this charge distribution is implemented by traversing of the nozzle jet, as directed to penetrate into the metal and slag bath from a solids injection lance, successively backwards and forwards and, in the case of coarse-sized materials, by traversing of the discharge from an oscillating conveyor. A preferred embodiment includes longitudinal extension of the furnace to include a gas-liquid reaction zone adapted for conducting refining reactions and adjusting metal temperature prior to discharging, as heated by a burner generating hot furnace gases which flow countercurrent to the general metal movement. The discharge of liquid metal and slag can be via tap hole, vacuum siphon or overflowing the annular lip of the discharge opening. The direct introduction of heat and selective introduction of oxygen along the gas-solid-liquid reaction zone is also preferred for effecting substantially complete combustion of furnace gases to CO2 and H2O before exhausting from the furnace. Recirculation of a major portion of the exhaust gases into the gas-liquid reaction zone is an optional feature.

摘要： 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.
摘要翻译：一种用于回收污染的废金属的装置和方法，更具体地说，一种设计用于熔化废料的改进的反射炉。测量从被污染的废料的熔化中挥发的烃的量，并将烟雾通入主炉中进行燃烧。随着烟雾中含有的燃料量的增加，燃烧器中燃料的量成比例地减少，同时氧气的数量保持不变。这将确保在炉内存在的燃料量和存在的氧气量完全燃烧，而不会在炉内或炉排气内积聚过多的游离氧或未燃烧的燃料。燃烧器将在贫燃条件下或在富燃料条件下运行，使得火焰温度低于化学计量燃烧时，燃烧器产生减少的NOx。
