Ironmaking 101 From Ore to Iron with Blast Furnaces

Oct 10 2017 Iron is mainly extracted from hematite Fe 2 O 3 and magnetite ores. Natural or direct shipping iron ores contain between 50-70 iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide FeO and ferric oxide Fe 2 O 3 via Fe 3 O 4 FeO Fe 2 O 3. A specialized type of coal called hard coal .

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 iron-bearing materials e.g. sintering coke-making and steel finishing processes such as shaping annealing and galvanizing.

Blast Furnace Introduction Definition Construction

Blast Furnace Introduction Definition Construction

May 21 2020 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.

BLAST FURNACE OPERATION AT A GLANCE 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.

Iron making basics Making iron is the first step in producing steel Iron should be produced of consistent quality. C 4.5 -5 Si 0.0.4 1..0 Mn 0.2-0.3 S 0.015- 0.040 P0.080-0.090 Rest Fe. Blast furnace is a reactor to produce iron. Ore reaches molten state and gets separated physically due to density from gangue and impurities.

THE BLAST FURNACE IRON PRODUCTION

THE BLAST FURNACE IRON PRODUCTION

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 gases are collected and cleansed. They are then used to help heat the air blast required if blast furnace is to reach the high temperatures needed to produce molten iron.
