Elemental carbon in iron and steel enterprises primarily enters in the form of coal and raw materials containing carbon. In the coking process, washed coal is indirectly heated, and dry distilled through the combustion of gaseous fuels (natural gas, coke oven gas, etc.) in the combustion chamber and is converted into secondary energy such as coke and coke oven gas (COG).

The absence of coke ovens and sinter plants in the FINEX process allow the capital investment of the FINEX to be reduced 20% compared to a conventional BF. Without cokemaking and sintering, the FINEX is more compact and takes less space. Continued cost advantages during operation can be realized as low cost and low quality raw materials (high alumina ore, high zinc ore, noncoking coals) use ...

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. During this process, it softens, then liquefies, and resolidifies into a hard porous material called "coke". This is not the cola soft drink.

It is thus important to ensure the coke is expansively tested. On a small testing scale, coke can be formed by the slow heating of coking coal in a refractory lined coal testing oven (CTO) to 1000 ˚C for 3 to 4 hours without the presence of air. The coal softens at a temperature of between 400 and 500 ˚C to form a plastic or liquid phase ...

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.

Coke oven gas is a valuable heating fuel that is used mainly within steel plants, for example, to fire blastfurnace stoves, to soak furnaces for semi finished steel, to anneal furnaces and lime kilns as well as to heat the coke ovens themselves (Kaegi et al., 1993). Coke is mostly produced from slottype byproduct coke ovens.
