  2. Melting-point apparatus - Wikipedia

    en.wikipedia.org/wiki/Melting-point_apparatus

    While the outward designs of apparatuses can vary greatly, most apparatuses use a sample loaded into a sealed capillary tube (melting-point tube), which is then placed in the apparatus. The sample is then heated, either by a heating block or an oil bath, and as the temperature increases, the sample is observed to determine when the phase change ...

  3. Melting - Wikipedia

    en.wikipedia.org/wiki/Melting

    Melting ice cubes illustrate the process of fusion. Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.

  4. Melt spinning - Wikipedia

    en.wikipedia.org/wiki/Melt_spinning

    There are many factors at play in even a basic melt spinning process. The quality and dimensions of the product are determined by how the machine is operated and configured. Consequently, there are many studies exploring the effects of variations in the melt spinner's configuration on specific alloys.

  5. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    The required temperature varies both in absolute terms and in terms of the melting point of the base metal. Examples: Iron oxide becomes metallic iron at roughly 1250 °C (2282 °F or 1523 K), almost 300 degrees below iron's melting point of 1538 °C (2800 °F or 1811 K). [5]

  6. Foundry - Wikipedia

    en.wikipedia.org/wiki/Foundry

    Melting metal in a crucible for casting A metal die casting robot in an industrial foundry. Melting is performed in a furnace. Virgin material, external scrap, internal scrap, and alloying elements are used to charge the furnace. Virgin material refers to commercially pure forms of the primary metal used to form a particular alloy.

  7. Melt electrospinning - Wikipedia

    en.wikipedia.org/wiki/Melt_electrospinning

    Different melt electrospinning machines have been built, with some mounted vertically and some horizontally. The approach to heating the polymer does vary and includes electrical heaters, heated air and circulating heaters. [3] One approach to melt electrospinning is pushing a solid polymer filament into a laser, which melts and is electrospun.

  8. Glass melting furnace - Wikipedia

    en.wikipedia.org/wiki/Glass_melting_furnace

    A glass melting furnace is designed to melt raw materials into glass. [1] Depending on the intended use, there are various designs of glass melting furnaces available. [2] [3] [4] They use different power sources. These sources are mainly fossil fueled or by fully electric power. A combination of both energy sources is also realized.

  9. Metallurgical furnace - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_furnace

    Other metallurgical furnaces have special design features or uses. One function is heating material short of melting, in order to perform heat treatment or hot working. Basic furnaces used this way include: A forge is the traditional metalsmith's hearth for heating metal while forging
