  2. Induction heating - Wikipedia

    en.wikipedia.org/wiki/Induction_heating

    Induction heating of 25 mm metal bar using 15 kW at 450 kHz. Keeping silicon in crucible molten at 2,650 °F (1,450 °C) for Czochralski crystal growth, 1956.. Induction heating allows the targeted heating of an applicable item for applications including surface hardening, melting, brazing and soldering, and heating to fit.

  3. 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 .

  4. Induction heater - Wikipedia

    en.wikipedia.org/wiki/Induction_heater

    Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.Supply (mains) frequency 50 Hz or 60 Hz induction heaters incorporate a coil directly fed from the electricity supply, typically for lower power industrial applications where lower surface temperatures are required.

  5. Induction shrink fitting - Wikipedia

    en.wikipedia.org/wiki/Induction_shrink_fitting

    Induction heating is a non contact heating process which uses the principle of electromagnetism induction to produce heat in a work-piece. In this case thermal expansion is used in a mechanical application to fit parts over one another, e.g. a bushing can be fitted over a shaft by making its inner diameter slightly smaller than the diameter of the shaft, then heating it until it fits over the ...

  6. Induction hardening - Wikipedia

    en.wikipedia.org/wiki/Induction_hardening

    Induction heating is a non contact heating process which uses the principle of electromagnetic induction to produce heat inside the surface layer of a work-piece. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I 2 R losses in the material.

  7. Induction forging - Wikipedia

    en.wikipedia.org/wiki/Induction_forging

    Induction heating is a non-contact process which uses the principle of electromagnetic induction to produce heat in a workpiece. By placing a conductive material into a strong alternating magnetic field, electric current is made to flow in the material, thereby causing Joule heating.

  8. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    Eddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces. The heat can be used for induction heating. The electromagnetic forces can be used for levitation, creating movement, or to give a strong braking effect. Eddy currents can also have undesirable effects, for instance power loss in transformers.

  9. 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]
