HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Integrated iron and steel mills produce steel by reducing iron ore to iron in a blast furnace and, subsequently, removing excess carbon and other impurities from the iron in a basic oxygen furnace. Other processes involve beneficiating iron ore (e.g., pelletizing), recycling of ironbearing materials (e.g.,
Iron Ore Processing for the Blast Furnace. Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and
Iron and Steelmaking (Study Support) Prof. Ing. Jiří Bažan, CSc. Doc. Ing. Ján Kret, CSc. Diagram of a blast furnace plant . is considered iron ore. From the chemical point of view, iron ores can be divided into four groups.
A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste
Apr 13, 2013 · gcse 2. Blast furnace extraction of iron recycling, steel making The raw materials needed limestone, coke, air and iron ore and the How do we extract iron from its mineral ores like the iron oxide ores . There are two ways to show the formation of the waste slag, which is mainly calcium silie. »More detailed
The unmelted iron ores still contain nonreduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave nonreduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can be almost completely reduced.
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
The production of 1 ton of iron requires 1.4 tons of ore or other iron bearing material 0.5 to General flow diagram for the iron and steel industry. In the basic oxygen process (BOP), molten iron from a blast furnace and iron scrap are refined. Chat Online
Fig. 1 Typical blast furnace. The charge of blast furnace possesses successive layers of iron ore, scrap, coke, and limestone and some steel scrap which is fed from the top of the furnace. Iron ore exists as an aggregate of ironbearing minerals. These mineral aggregates are oxides of iron called hematite, limonite, and magnetite.

Blast Furnace Process. The blast furnace is a countercurrent gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from
Blast furnace – Wikipedia, the free encyclopedia. Learn more » A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper.
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 chemical 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
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
