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").

HOW A BLAST FURNACE WORKS - Foundry Gate

Combustion process. The iron in the processed ores must be dissolved out by chemical 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 ...

Pig iron - Wikipedia

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.

Iron Furnace History in Ohio - Olde Forester

The Pig iron produced from the blast furnace contains 90 to 92% of iron. Other composition of the pig is carbon (1-5%), manganese (1-2%), sulphar and phosphorus (1-2%). The carbon is very important element in the iron which exists in iron in two forms, either in a free form as graphite or in a combined form as cementite and pearlite.

Granulated Pig Iron (GPI) | International Iron Metallics ...

The blast furnaces continue throughout the world to provide the predominant, if not the sole means of producing pig-iron. Their design has practically remained unchanged. They have however grown to an incredible extent in size and efficiency. The capacity of old blast furnaces was around 15000 kN of pig-iron …

Pig iron and Blast Furnace | Informational Encyclopedia

Aug 22, 2017· However, these furnaces work slightly differently than they did 2000 years ago. Today, coke is used to melt the iron ore to create pig iron. Oxygen is then used to further transform the pig iron into steel. This process requires a continual supply of coke as well as very large furnaces that produce high CO2 emissions. Electric Arc Furnaces

Blast Furnace. After mining, various kinds of iron ores are brought to the blast furnace which is the starting process for refining iron ores or mined ores and for the production of pig iron. Blast furnace was invented in 14th century. A typical blast furnace along with its various parts is shown in Fig. 1.

I. PIG IRON IS MADE IN A BLAST FURNACE BY SMELTING …

The blast furnace produces iron from iron ore. Iron ore and coke are fed alternately from the furnace top, while a blast of hot air is blown from the furnace bottom. The CO2 gas generated by the combustion of coke reduces iron ore to iron. As temperature in the furnace reaches as high as 2000°C, molten iron is removed from the bottom of the ...
