Description
Blast furnaces. These furnaces are operated by the Sloss-Sheffield Steel and Iron Company, Birmingham, Alabama, USA. They were originally built in the 19th century. Dating from the 1930s, this photograph is from the Albert T. Keller collection of the American Iron and Steel Institute. The collection consists of historical photographs of blast furnaces used in the iron and steel industry. A blast furnace is where iron ore is heated to high temperatures in the presence of oxygen, with the carbon content controlled to produce types of steel (an alloy of iron and carbon).
