  2. Induction heating - Wikipedia

    en.wikipedia.org/wiki/Induction_heating

    Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...

  3. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    Combining copper with tin and/or arsenic in the right proportions produces bronze, an alloy that is significantly harder than copper. The first copper/arsenic bronzes date from 4200 BC from Asia Minor. The Inca bronze alloys were also of this type. Arsenic is often an impurity in copper ores, so the discovery could have been made by accident.

  4. Induction furnace - Wikipedia

    en.wikipedia.org/wiki/Induction_furnace

    An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. [1] [2] [3] Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel, copper, aluminum, and precious metals.

  5. Copper in heat exchangers - Wikipedia

    en.wikipedia.org/wiki/Copper_in_heat_exchangers

    The copper heat pipe transfers thermal energy from within the solar tube into a copper header. As the solution circulates through the copper header, the temperature rises. Other components in solar thermal water systems that contain copper include solar heat exchanger tanks and solar pumping stations, along with pumps and controllers.

  6. Induction brazing - Wikipedia

    en.wikipedia.org/wiki/Induction_brazing

    Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .

  7. Refining (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Refining_(metallurgy)

    In one of the previous melting stages, lead was added. Gold and silver preferentially dissolved in this, thus providing a means of recovering these precious metals. To produce purer copper suitable for making copper plates or hollow-ware, further melting processes were undertaken, using charcoal as fuel. The repeated application of such fire ...

  8. Liquation - Wikipedia

    en.wikipedia.org/wiki/Liquation

    The copper-lead alloy created can be tapped off and cast into large plano-convex ingots known as ‘liquation cakes’. As the metals cool and solidify the copper and the silver-containing lead separate as they are immiscible with each other. The ratio of lead to copper in these cakes is an important factor for the process to work efficiently ...

  9. Vacuum arc remelting - Wikipedia

    en.wikipedia.org/wiki/Vacuum_arc_remelting

    Ideally, the melt rate stays constant throughout the process cycle, but monitoring and control of the vacuum arc remelting process is not simple. [5] This is because there is a complex heat transfer occurring involving conduction, radiation, convection within the liquid metal, and advection caused by the Lorentz force. Ensuring the consistency ...
