  2. Induction furnace - Wikipedia

    en.wikipedia.org/wiki/Induction_furnace

    The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting. Most modern foundries use this type of furnace, and many iron foundries are replacing cupola furnaces with induction furnaces to melt cast iron, as the former emit much dust and other pollutants ...

  3. 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 ...

  4. 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.

  5. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.

  6. Flash smelting - Wikipedia

    en.wikipedia.org/wiki/Flash_smelting

    Flash smelting with oxygen-enriched air (the 'reaction gas') makes use of the energy contained in the concentrate to supply most of the energy required by the furnaces. [ 4 ] [ 5 ] The concentrate must be dried before it is injected into the furnaces and, in the case of the Outokumpu process, some of the furnaces use an optional heater to warm ...

  7. Metallurgical furnace - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_furnace

    A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy; processing metals with heat is even its own engineering specialty known as pyrometallurgy.

  8. Vacuum induction melting - Wikipedia

    en.wikipedia.org/wiki/Vacuum_induction_melting

    Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum. The first prototype was developed in 1920. [1] Induction heating induces eddy currents within conductors. Eddy currents create heating effects to melt the metal. [2] Vacuum induction melting has been used in both the aerospace and nuclear industries. [2]

  9. Refining (metallurgy) - Wikipedia

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

    The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper (II) sulfate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode. However ...
