Used in steelmaking, but it is not indispensable like met coal. It is a softer, non-coking coal which is pulverized and injected into the blast furnace to supply heat, which in return reduces energy use and emissions. It does not play a role in the iron-steel conversion, and cannot replace hard coking coal .

COKE PRODUCTION FOR BLAST FURNACE IRONMAKING

The coal-to-coke transformation takes place as follows: The heat is transferred from the heated brick walls into the coal charge. From about 375°C to 475°C, the coal decomposes to form plastic layers near each wall. At about 475°C to 600°C, there is a marked evolution of tar, and aromatic hydrocarbon compounds, followed by
