The Cedar Creek Furnace (also known as the Alabama Iron Works) is a former blast furnace site near Russellville in Franklin County, Alabama, United States. It was the first iron ore furnace in Alabama , preceding an industry that would come to dominate the state's economy in the late 19th and early 20th century.
The iron ore is introduced into the furnace upstream and mixed with a small amount of fuel, typically hard coal. [21] After 6 to 8 hours, [22] it exits the furnace as pre-reduced iron ore at 1,000 °C. The amount of iron recovered ranges from 94% to 97.5% of the initial iron in the ore. [21]
Direct-reduced iron can be produced from iron ore as it reacts with atomic hydrogen. Renewable hydrogen allows steelmaking without fossil fuels. Direct reduction occurs at 1,500 °F (820 °C). The iron is infused with carbon (from coal) in an electric arc furnace. Hydrogen electrolysis requires approximately 2600 kWh per ton of steel. Hydrogen ...
Founded in 1898, it is one of the oldest businesses in Lethbridge. Initially established to serve the coal industry in southern Alberta, LETH IRON has evolved over the past century into a jobbing iron foundry, providing castings for clients in various sectors such as agriculture, automotive, construction, oil & gas, and rail across North ...
By this time, 14,500 people were employed in the works in and around Ebbw Vale. [12] The original choice for the site was due to its co-location with both iron ore and coal. However, by the 1970s the industry had changed to one of sheer volume, with supplies drawn from vast mines and pits.
The best yield of iron achievable from dry puddling is one ton of iron from 1.3 tons of pig iron (a yield of 77%), but the yield from wet puddling was nearly 100%. The production of mild steel in the puddling furnace was achieved circa 1850 [ citation needed ] in Westphalia , Germany and was patented in Great Britain on behalf of Lohage, Bremme ...
In the 1800s, making a ton of steel required a greater weight of coal than iron ore. Therefore, it was more economical to locate closer to the coal mines. Pittsburgh , Pennsylvania , surrounded by large coal deposits and at the junction of three navigable rivers, was an ideal location for steelmaking.
The Iron Rolling Mill (Eisenwalzwerk), 1870s, by Adolph Menzel. Casting at an iron foundry: From Fra Burmeister og Wain's Iron Foundry, 1885 by Peder Severin Krøyer. An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made.
