  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. Smelting - Wikipedia

    en.wikipedia.org/wiki/Smelting

    Most early processes in Europe and Africa involved smelting iron ore in a bloomery, where the temperature is kept low enough so that the iron does not melt. This produces a spongy mass of iron called a bloom, which then must be consolidated with a hammer to produce wrought iron. Some of the earliest evidence to date for the bloomery smelting of ...

  4. 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]

  5. 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.

  6. Steelmaking - Wikipedia

    en.wikipedia.org/wiki/Steelmaking

    Blast furnaces remove oxygen and trace elements from iron and add a tiny amount of carbon by melting the iron ore at 1,700 °C (3,090 °F) in the presence of ambient oxygen and coke (a type of coal). The oxygen from the ore is carried away by the carbon from the coke in the form of CO 2. The reaction: Fe 2 O

    "You don't really have to do this step, but if you do, bake the dry pan in the oven at 500°F for an hour and a half, or up to three hours if you want," he explains. "This will form iron black ...

  8. Bloomery - Wikipedia

    en.wikipedia.org/wiki/Bloomery

    A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...

    “Make sure you let it cool down to a temperature that you can handle without a cloth or glove,” Stewart explains. Fill the pan with warm water and mild dish soap, allowing it to sit for 15-20 ...
