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 ...
Hashino iron mining and smelting site (橋野高炉跡, Hashino kōro ato) is the ruins of an iron smelting and primitive blast furnace built by the Tokugawa shogunate during the final years of the Edo period in the Hashino neighborhood of the city of Kamaishi, Iwate in the Tohoku region of northern Japan.
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.
Even so, the establishment was to play an important role in the Industrial Revolution. It was at Wilsontown that raw pit coal was first successfully used to fuel a blast furnace, with enormous savings of coke; it has been described as "the making of the iron trade in Scotland" and "one of the grandest epochs in the history of the iron manufacture".

Blast furnace 3, including the cast house, is one of the main components of the museum and features numerous information plates, exhibition pieces and documentary films on monitors. The blast furnace also serves as an observation platform. An elevator has been installed. A colorful light installation illuminates the blast furnace at night.

the production of ferromanganese in the blast furnace requires a high manganese yield and therefore high basicities, up to i = 1.7 or 1.8 (bearing in mind that in this particular case, the index corresponds to = [] + [] + [] []!). Meltability is a secondary consideration in this case, as slag temperatures can reach 1,650°C (instead of 1,450°C ...
