  2. Wood-burning stove - Wikipedia

    en.wikipedia.org/wiki/Wood-burning_stove

    A wood-burning stove (or wood burner or log burner in the UK) is a heating or cooking appliance capable of burning wood fuel, often called solid fuel, and wood-derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal (usually cast iron or steel) closed firebox, often lined by fire brick, and one or more ...

  3. Slag - Wikipedia

    en.wikipedia.org/wiki/Slag

    The general term slag may be a by-product or co-product of smelting (pyrometallurgical) ores and recycled metals depending on the type of material being produced. [1] Slag is mainly a mixture of metal oxides and silicon dioxide. Broadly, it can be classified as ferrous (co-products of processing iron and steel), ferroalloy (a by-product of ...

  4. Pitting corrosion - Wikipedia

    en.wikipedia.org/wiki/Pitting_corrosion

    Pitting corrosion. Appearance. Severe pitting corrosion problems caused by chloride ions on a truss beam of the Nandu River Iron Bridge (Hainan Province, China) leading to the complete rupture of a metallic element. Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the random creation of small holes in metal.

  5. Tempering (metallurgy) - Wikipedia

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

    Tempering (metallurgy) Differentially tempered steel. The various colors produced indicate the temperature the steel was heated to. Light straw indicates 204 °C (399 °F) and light blue indicates 337 °C (639 °F). [1][2] Tempering is a process of heat treating, which is used to increase the toughness of iron -based alloys.

  6. Ferrous metallurgy - Wikipedia

    en.wikipedia.org/wiki/Ferrous_metallurgy

    Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, [1] were made from meteoritic iron-nickel. [2] It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in ...

  7. Rust - Wikipedia

    en.wikipedia.org/wiki/Rust

    Wrought iron. Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron (III) oxides (Fe 2 O 3 ·nH 2 O) and iron (III) oxide-hydroxide (FeO (OH), Fe (OH) 3), and is typically associated with the corrosion of refined iron.

  8. Annealing (materials science) - Wikipedia

    en.wikipedia.org/wiki/Annealing_(materials_science)

    In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate ...

  9. 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 ] The overall shape is cylindrical and the equipment is ...
