A blast furnace is a special type of cylindrical furnace, which is basically used for the purpose of smelting. So, the industrial metals can be extracted from their ores like iron, pig iron, or copper. The word ‘blast’ gives the idea of combustion air which is forcefully supplied or produced to the atmospheric pressure above. In past times, furnace...
It is defined as a metallurgical furnace which is used to extract metals primarily from its ores of iron and copper. The fuel contains a mixture of flux that is particularly limestone where iron ore is available, and coke is supplied and pumped through the top of the furnace. On the other hand, the bottom of the furnace is attached with a series of...
A Blast Furnace is consist of the following sections: 1. Furnace Proper 2. Cast House 3. Stoves 4. Raw Material Storage Section 5. Raw Material Charging Section 6. Gas Cleaning Point 7. Slag Dumping Area 8. Pulverised coal Inoculation So let me discuss 1 by 1.
A blast consisted of the following parts: 1. Hoppers 2. Adjustable Gates 3. Rotating Chute 4. Fire brick 5. Combustion 6. Gas burner 7. Carbon brick 8. Taphole 9. Tuyere
The blast furnace is constructed in the form of a tall structure, placed with special kind of bricks (Fire Clay bricks) which are resistant to decomposition by any of the environmental attacks. These bricks are the outlines to enable the expansion of charged materials. As soon as melting starts to occur, these brick heat and reduces in size. The co...
The working phenomenon of this blast furnace is very simple. In order to smelt iron from its ores, first of all, limestone flux, coke, and iron ore are introduced into the top face of the furnace. They are allowed to enter with very precision order so that gas flow and other chemical reactions can be controlled effectively. The gas which is very ho...
There are numerous applications of blast furnaces that are being practiced in various big as well as small industries mostly.In general, it is used to produce Pig iron from its ore.It is used in process plants.The slag of the blast furnace has hydraulic properties which are used in cement as a additivesThe blast furnaces help to save fuel from 82 to 87 MJ/t-HM which are installed in the industries. In Japan, it was observed that around 0.125 GJ/t-pig iron has been saved in a 1 Mt/y by only recovering 50% of the stove flue gases. Hot blast stoves are generally used to recuperate heat which helps to reduce energy demand by 0.26 GJ/t-HM and globally...
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 supplied above atmospheric pressure. [1]

Oct 20, 2021 · The basic working principle of a blast furnace is the change in the chemical affinity (Affinity of any element refers to the tendency of that element to make bonds with any other dissimilar) between 3 different elements. For example, there are three different elements namely A, B, and C.
Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Lime-stone, Pyroxenite, Quartzite reacting with oxygen from pre heated air.
Jun 21, 2018 · In the blast furnace, the iron ore reacts with the carbon contained in the coke to form grey or white pig iron. Combustion process The iron in the processed ores must be dissolved out by chemical processes.
