    en.wikipedia.org/wiki/Valley_Furnace

    The furnace was constructed circa 1847 by George W. Bryan, who named the furnace "fanny" for his wife. . Unlike earlier bloomery furnaces that produced wrought iron, the Valley Furnace was a blast furnace that produced pig iron using a bellows to induce a forced draft, using charcoal as a fuel. Ore was provided from surface mines that exploited ...

    en.wikipedia.org/wiki/Blast_furnace

    Blast furnaces are currently rarely used in copper smelting, but modern lead smelting blast furnaces are much shorter than iron blast furnaces and are rectangular in shape. [76] Modern lead blast furnaces are constructed using water-cooled steel or copper jackets for the walls, and have no refractory linings in the side walls. [77]

    Iron ore pellets produced by LKAB, from ore mined in northern Sweden. Pellets are a processed form of iron ore utilized in the steel industry, specifically designed for direct application in blast furnaces or direct reduction plants. These pellets are spherical in shape, with diameters ranging from 8 to 18 millimeters.

    The next year, much of the plant was replaced with more modern equipment. [5] James Gayley developed the dry-air blast technique at Isabella Furnace and the Edgar Thomson Steel Works between 1885 and 1904. The discovery reduced the cost of a ton of pig iron by $0.50 to $1.00 and made it possible to produce uniform quality metal regardless of ...

    When construction on a house near the site began in the 1950s, “they found a lot of artifacts from the iron furnace,” Stout said, “including a cannon fragment.

  8. Direct reduction (blast furnace) - Wikipedia

    en.wikipedia.org/wiki/Direct_reduction_(blast...

    Direct reduction is the fraction of iron oxide reduction that occurs in a blast furnace due to the presence of coke carbon, while the remainder - indirect reduction - consists mainly of carbon monoxide from coke combustion. It should also be noted that many non-ferrous oxides are reduced by this type of reaction in a blast furnace.
