12.2 Coke Production

The coking time is determined by the coal mixture, moisture content, rate of underfiring, and the desired properties of the coke. When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and to 48 hours for foundry coke. Coking temperatures generally range from 900° to 1100°C (1650° to

12.2 Coke Production

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

Coking Coal - an overview ScienceDirect Topics

Around 0.6 t (600 kg) of coke produces 1 t (1000 kg) of steel, which means that around 770 kg of coal are used to produce 1 t of steel through this production route [10]. The most commonly applied process for steel making is the integrated steel-making process via the blast furnace–basic oxygen furnace which produces about 70% of the world’s steel.

Coking coal of the United States—Modern and historical ...

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, Virginia , and West Virginia.
