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 ...

Calcination of Limestone

Some limestone, due to its crystalline structure, disintegrates during the calcination process. This type of limestone is not useful for calcining. There is some other limestone whose behaviour is the opposite. This type of limestone become so dense during calcination that it prevents the escape of CO2 and become non porous.
