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.
Iron Ore Smelting Process Using Modern Blast Furnaces. Although the basic ingredients of an iron ore blast furnace has changed little over the last hundred years or so, the furnaces themselves have been modernized to improve efficiency and the purity of the iron and steel.
The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, oxides, dross, and reverberatory slag.

The main purpose of a blast furnace is to convert the iron ores, mined in the form of hematite or magnetite, to pig iron. The blast furnace is in use after the iron ores have been converted into iron-rich pellets, and the coke and limestone prepared in the considerable amounts.
A blast furnace is a type of furnace for smelting whereby the combustion material and ore are supplied with air from the bottom of the chamber such that the chemical reaction does not take place only at the surface. Typically this is used for the production of pig iron from iron ore.. History. The oldest known blast furnaces were built in Han China in the 1st century BC.
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.
limestone processing blast furnace - saplgroup. Limestone Used In Blast Furnace .za. 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 In a blast ...
Calcium hydroxide is used for water treatment, acid neutralizing, and as a lubricant for wire drawing. All the other limes are used as fluxes in the sintering plant, blast furnace or steel producing furnaces. In the production of self flux or super-flux sinter, high calcium and dolomitic limestone fines, are used.
Oct 20, 2011· The first thing required is a blast furnace, which is filled with iron ore, coke, and crushed limestone. Then it is fired and a strong air blast is blown upwards through the furnace.

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and lizenithne are dumped into the top, and preheated air is blown into... Blast furnace . 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.
Limestone Consumption In Blast Furnace. The ougree company, now thlly convinced of the immense advantages derivable from the use of lime, is occupied with the construction of kilns heated by the blast furnace gasesiege, december 21 the use of caustic lime, instead of limestone, in blast fgrnaces.
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which ...
Jul 07, 2017· Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for .
