WebThe 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. WebA process of smelting iron ores into hot metal. Iron and coal must be solidified before they can be used in a blast furnace. Sintering and coking are the processes of solidifying iron and coal, respectively. Blast furnaces, which can reach heights of 100 meters, are used to stack the pretreated iron and coal.
