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. An understanding …

A noncaking coal is always noncoking but a caking coal does not always make good coke. Solid-based DRI processes prefer a noncaking and noncoking coal, but a coking coal is desirable for BF operation [39, 40]. For RK-grade coal in India, the specification for Caking Index is a maximum of 3 [38].

To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.

The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled and screened into pieces ranging from one inch to four inches. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong.

Coke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed.

Coal-tar pitch is produced by distillation of the crude coke-oven tar (obtained during the high-temperature treatment of coal to make coke or natural gas). Pitch materials are usually thick, black, or dark brown liquids or semi-solids with a naphthalene-like odor. Coal-tar pitch can typically be recognized by its sharp, burning odor.
