A mobile melting device for consolidating contaminated scrap and to a corresponding method. The melting device has a crucible chamber and a crucible base. The crucible is arranged on the crucible base during operation, and the crucible base and the crucible chamber together form a gas-tight furnace housing. It is thus possible to carry out the method in a vacuum or under protective gas such that even a reactive material can be consolidated. The melting device can be assembled and disassembled with little effort.

A pot furnace for calcining petroleum coke at low temperature may include a pot, and a cooling water jacket and a flame path below the pot. The flame path may include eight layers. An inlet of a first flame path layer may be in communication with a volatile channel in the front wall, and is provided with a first flame path layer flashboard. An eighth flame path layer may be in communication with a communication flue. Flue gas may be discharged out of the furnace body through a main flue. A furnace bottom cooling channel may be provided below the eighth flame path layer.

A strip casting system for aluminium and/or aluminium alloys comprising a casting furnace and a revolving chill mould having a casting gap. The revolving chill mould is designed as a roll pair, roller pair, caterpillar pair or belt pair. The strip casting system has an active means for transporting metal melt from the casting furnace to the casting gap and a casting region arranged in front of the casting gap. The casting region is delimited on one side by the revolving chill mould. A melt pool is formed in the casting region, from which metal melt flows or is drawn into the casting gap. The casting furnace is connected to the casting region by a pipe system with means for feeding the metal melt into the casting region, which can feed the metal melt to the casting region below the surface of the melt pool formed in the casting region.

In an aspect, a method of manufacturing a high purity copper-based alloy comprises providing in a melting furnace a feedstock and melting the feedstock. The method additionally includes bubbling an inert gas into the molten copper-based alloy to form the high purity copper-based alloy. Aspects are also directed to an apparatus and a method of fabricating an apparatus for manufacturing the high purity copper-based alloy.

The application basically comprises supplying a high-temperature ultra-high vacuum furnace, the sole chamber of which is metal, in which an electrically conductive crucible, preferably made of tantalum, is placed onto an insulating support, preferably a ceramic, and is induction heated by a winding wound around the crucible. The insulating tube, preferably made of quartz, that is arranged between the induction winding and the crucible, advantageously acts as a surface on which the condensable species can condense. The quartz insulating tube especially allows the induction winding to be protected.

A device for producing purified, especially high-purity, magnesium includes a reactor for vacuum distillation that is extended along a longitudinal axis (L). The reactor defines a reactor inner chamber having a heating region for heating magnesium. A crucible forms a crucible inner chamber for receiving purified magnesium vaporized and condensed by the device. A radial projection in the heating region defines a contact surface that extends essentially transverse to the longitudinal axis (L) and forms an essentially sealed connection with an edge of the crucible adjacent to the crucible inner chamber.

The invention relates to a process for processing hard metal, in particular hard metal scrap, wherein the hard metal is alloyed with a low-melting alloy metal in a reaction space of a reactor (10) with a heat supply, wherein the alloy metal is converted into a vapor phase in the presence of inert gas, and wherein the alloy metal is subsequently at least partially condensed in a condensation step, and wherein an overpressure relative to ambient pressure is present in the reaction space at least during the condensation phase. According to the invention, provision is made in particular for the inert gas to be permanently supplied to the reaction chamber at least temporarily during the condensation phase from an inert gas source (60) disposed outside of the reaction chamber via an inert gas supply line (61), and for the inert gas to be discharged from of the condenser (30) into the environment at least at certain intervals during the condensation phase. In this way, the equipment required can be significantly reduced compared to prior art hard metal chemical extraction processes.
