What is coking coal, and where is it used?

2021-8-17 · What is the use of coking coal? Coking coal is the main ingredient in the steel manufacturing process. Around 770kg of metallurgical coal is required to manufacture nearly one ton of steel. Steel can be produced via two main processes, electric arc furnace (EAF) or through blast furnace-basic oxygen furnace (BF-BOF).

The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace – Basic Oxygen Furnace. Around 0.6 tonnes (600 kg) of coke produces 1 tonne (1000 kg) of steel, which means that around 770 kg of coal are used to produce 1 tonne of steel through this production route.

12.2 Coke Production - US EPA

2015-9-10 · 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".

What is Coking Coal - Aspire Mining Limited

Coke is produced by heating coking coals in a coke oven in a reducing atmosphere. As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process.

Coal & steel | World Coal Association

The coking coal is crushed and washed. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours. During this process, by-products are removed, and coke is produced. Iron
