Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the cokemaking 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 volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are ...
