Blast furnace - Wikipedia
A 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 "forced" or supplied above atmospheric pressure.

A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest stone reactor.Blast furnaces are also called high ovens.. A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside ...
Blast Furnace - an overview | ScienceDirect Topics
Blast furnace gas is produced during the iron oxide reduction in blast furnace iron making in which iron ore, coke and limestone are heated and melted in a blast furnace and is an indigenous process gas of the steelworks industry (Pugh et al., 2013).
Blast Furnace - ScienceAid
Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500s.
Ironmaking 101 – From Ore to Iron with Blast …
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.
Iron processing - Iron making | Britannica
7-7-2020 · Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from stone combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
Iron Ore Processing for the Blast Furnace
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").

4-10-2016 · blast furnace process for iron making : Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as hematite contain iron(III) oxide, Fe 2O 3.
Extraction of Iron | Metallurgy | Blast Furnace and …
It’s a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulfur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
Blast furnace process - tec-science
Combustion process. The iron in the processed ores must be dissolved out by stone processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the ...
The Blast Furnace
Once a blast furnace is started it will continuously run for four to ten years with only short stops to perform planned maintenance. The Process . Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches.
Blast Furnace - an overview | ScienceDirect Topics
The blast furnace process has auxiliary equipment associated with it. This auxiliary equipment and the gaseous pathways inside a blast furnace process are shown in Figure 2. The blast furnace process can be briefly described as follows. Iron oxides, flux agents, and metallurgical coke are added to a skip car at the stock house.

PROCESSES INSIDE THE BLAST FURNACE
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 chemistry of steelmaking. Blast furnace.
The production of iron in a Blast Furnace is a continuous process. The furnace is heated constantly and is re-charged with raw materials from the top while it is being tapped from the bottom. Iron making in the furnace usually continues for about ten years before the furnace linings have to be renewed.
