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.

Blast furnacebasic oxygen furnace uses iron ore as its base raw material that accounts over just 50% of BOF steel costs, and electric arc furnace uses scrap as its base that represents around 75% of EAF steel cost. The Basic Oxygen Steelmaking process differs from the EAF is that BOF is selfsufficient in energy. The primary raw materials for the BOP are 7080% liquid hot metal from the blast ...
The metallic iron in iron ore exists in the state of iron oxide. Therefore, extracting metallic iron from iron oxide is the most basic reaction for smelting pig iron. At present, ferro silicon, silicon briquette or other reducing agents are mainly used to deprive iron ore of oxygen, which is the basic method of blast furnace steelmaking.
blast furnace process for iron sand functionphotoco. blast furnace process The iron ore concentrate is now mixed and ready for the pelletizing process Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2")
· Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking sufficiently high temperatures, the carbon can participate directly in the ...
process, the iron from the blast furnace is converted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace (EAF) from scrap steel and, in some cases, from direct reduced iron. BOF is typically used for hightonnage production of carbon steels, while the EAF is used to produce carbon steels and low tonnage specialty steels. An emerging technology ...
Molten iron and slag exit the blast furnace through the taphole into a refractorylined trough. The molten slag, which floats on top of the iron, is separated from the iron by the skimmer block. The molten iron flows under the skimmer into an iron pool and then over the iron dam to the refractorylined iron runner. The iron runner directs the molten iron to a series of torpedo ladle cars for ...

The production of iron in a blast furnace is an important industrial process, although other methods for iron production are also in use. The basic idea involves the heating of an iron oxide, often haematite, Fe 2 O 3, with carbon. A jet of air is used to burn the carbon to form the gas carbon dioxide. The carbon dioxide then reacts with more carbon to form carbon monoxide. Carbon monoxide is ...
· After iron ore is mined it is send to the blast furnace. Iron is extracted from its ore in a blast furnace. The structure of a blast furnace. Image credit The oxide ores are reduced to iron by removing the oxygen from them. Coke, limestone and iron ore are fed into the top of the furnace. Hot air is forced through tuyeres (openings)
· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Iron from the blast furnace is an alloy of about 96 per cent iron with carbon and some other impurities. It is hard, but too brittle for most uses. So, most iron from the blast furnace is converted into steel by removing some of the carbon. Show Video. Try the free Mathway calculator and problem solver below to practice various math topics.

limestone or dolomite and silica sand) are added to the blast furnace or steelmaking furnace to remove impurities from the iron ore, steel scrap, and other ferrous feeds. Slag protects the liquid metal from outside oxygen and maintain temperature by forming a lid. As slag is lighter than the liquid metal, it floats and can be easily removed. There are three main types of marketed ironmaking or ...
Blast furnace dust accounted for 27%36% of the total mercury output for the whole iron and steel production process. The recycling of blast furnace dust could greatly increase the atmospheric mercury emissions and should not be conducted. The mercury emission factors for the coke oven, sintering machine and blast furnace were /ton steel, and for the electric furnace it was 0 ...

Iron ore, limestone and coke is the ''stock' of the blast furnace. This is fed into the furnace at its top. A variety of processes take place within the blast furnace, as the 'stock' slowly moves downwards and temperatures increase. The removal of oxygen through the chemical process called 'reduction' is crucial (oxygen combines with carbon monoxide, forming carbon dioxide gas ...
