Coke and How it's Made. Coke is a fuel used in the steelmaking process that is created by heating coal in the absence of air. Myth: The process of coke manufacturing is very complex and cannot be understood by anyone other than a scientist or engineer. Reality: The manufacturing of coke involves a number of different processes.

In a general way, coke is as near a pure carbon as may be had; as near an uncrystalized diamond as can be made. The beehive coke oven transforms the soft, crumbling bituminous coal into a hard, porous substance which will "stand up stiff-backed" under a ponderous load of iron ore and limestone in the blast furnace, where coke is chiefly used.

1.1 Coal, coke and the prediction of their properties. Metallurgical coke, derived from the pyrolysis of selected coals, plays several critical roles in the ironmaking blast furnace (Babich and Senk 2013; Bertling 1999; Biswas 1981).As a structural support, and source of permeability for the layers of softening iron materials, the selection of an …

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, ia, …
