  2. 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]

  3. 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

  4. 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.

  5. 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.

  6. Cupola furnace - Wikipedia

    en.wikipedia.org/wiki/Cupola_furnace

    A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Ni-resist iron and some bronzes. The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from 1.5 to 13 feet (0.5 to 4.0 m). [1]

  7. Metalworking - Wikipedia

    en.wikipedia.org/wiki/Metalworking

    Drilling a hole in a metal part is the most common example of a chip producing process. Using an oxy-fuel cutting torch to separate a plate of steel into smaller pieces is an example of burning. Chemical milling is an example of a specialty process that removes excess material by the use of etching chemicals and masking chemicals.

  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. 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 ...
