Blast furnace process

Blast furnace process. By. tec-science - 06/21/2018. 28377. 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. This requires an element that binds oxygen more strongly than iron.

Steel Production

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
