A system for adding molten lithium and inert gas in a molten aluminium or aluminium alloy melt including, a crucible defining a chamber for melting and storing molten metal, in particular molten lithium; the crucible having a sealed lid; an inert gas delivery system for maintaining chamber overpressure using inert gas; a conduit for withdrawing a portion of the molten metal from the crucible. The conduit arranged with respect to the crucible or the sealed lid so the conduit inlet can be moved below and above the molten metal surface level and arranged for feeding molten metal from the crucible to a separate holding furnace with the help of overpressure when the conduit inlet is below the molten metal surface level and arranged for feeding inert gas from the crucible to the separate holding furnace when the conduit inlet is above the molten metal surface level.

A dry-break electrical disconnect is provided between an induction melting furnace and a component of the electric induction melting assembly in which the furnace is removably installed for melting in a vacuum or otherwise controlled environmental chamber. Electric power connections are made to the induction melting furnace in a sealed interior volume of the assembly component that can be pressurized and of a different environment than that in the controlled environmental chamber. The assembly component may be a tilting cradle installed in the controlled environment chamber.

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.

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.

Melting plant having a melting chamber which by way of a gas protection hood is separated from the environment, wherein the gas protection hood or another part of the melting chamber encasement has a lead through in which an electrode rod for moving an electrode to be melted is guided in a gas-tight manner by way of a sealing means. Hydraulic or pneumatic equalisation means, for exerting on the electrode rod equalisation forces which are in a proportional correlation with the gas pressure prevailing within the melting chamber are provided so as to compensate for the gas-pressure forces acting on the electrode rod.
