Blast furnace | Definition, Temperature, Diagrams, & Facts
WEBblast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top.
Blast furnace - Wikipedia
WEBA blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [citation needed]
Steel Production - American Iron and Steel Institute
WEBSteel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day.
Global Blast Furnace Tracker - Global Energy Monitor
WEBThe Global Blast Furnace Tracker (GBFT) is a worldwide dataset of blast furnace units. It tracks each of the furnaces at iron and steel plants in GEM’s Global Steel Plant Tracker (GSPT), which includes plants with a crude iron or steel capacity of 500 thousand tonnes per annum (ttpa) or more, as well as those that have been proposed or under ...
Blast Furnace Process - Steel Museum
WEBA blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF.
WEBbosh profile minimized by inserting cooling plates/bars through the furnace shell, and high-accuracy, high-speed sensors introduced for stabilizing furnace operation. Top combustion hot stoves have been introduced, and blast temperature raised …
Blast Furnace - an overview | ScienceDirect Topics
WEBA blast furnace is a counter-current gas-solid reactor where the ascending gas reacts with the descending solid bed, producing hot metal as the main product.

Ironmaking 101 – From Ore to Iron with Blast Furnaces
WEBOct 10, 2017 · Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.
