Deze pagina vertalen

Metallurgical coal (also called "met" coal) is an important raw material used in the steelmaking process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.

Coal was made out of the ancient plants, 300 million years ago, even before dinosaurs, when huge plants started sedimentation in swamps. In millions of years that followed, mud was frothed over remains, transforming in that process huge heat in to a pressure, and all these factors combined gave ideal conditions for coal's "birthing place".
