The furnace is charged from the top with . Blast furnaces, converters and coke ovens produce large quantities of gases in the process of iron and steel manufacturing.
Blast 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 furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.

For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.
The limestone mixes with impurities in the iron to form slag. Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production.
Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone.
According to the source, it typically takes 1.5 tons of iron ore and around 450kg of coke to produce a tons of pig iron, the raw iron that comes out of a blast furnace. More information Region
Raw materials and fuel material decline with the furnace smelting process, the falling furnace burden meets with rising coal gas to successively take place heat transmission, reduction, melt, decarburization and then produce pig iron. The impurity in iron ore raw material is combined with flux added into the furnace forming slag, molten iron in ...
All iron produced in blast furnace whether in molten state or cast into pigs is called pig iron. Iron ore, coke and limestone are charged into a blast furnace to produce pig iron. The composition of pig iron varies with the quality of ore and operation of the blast furnace. ... The quantity of phosphorus present in pig iron varies from 0.1 to 2.0%.
Typically, it takes 1.6 tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of a blast furnace. Some of the coke can be replaced by injecting pulverised coal into the blast furnace. Iron is a common mineral on the earth's surface.
