The usual practice in the manufacture of coke is to apply external heat to the oven containing the coke and maintaining the necessary temperature for a long time, so that the gases are driven from the coal, leaving the carbon in the form of coke. This process is usually a long one, requiring twentyfour hours or more for its accomplishment.

Metallurgical coal, also known as coking coal or coke coal, is a highquality type of coal that possesses unique properties. This specific type of coal is predominantly used in the steelmaking industry due to its ability to produce high temperatures and low smoke emissions. One of the essential properties of metallurgical coal is its carbon ...

A coke oven is a device used to produce coke, a product that is derived from coal. The mixing and heating of bituminous coal at temperatures ranging from around 1832° to 3632°F (1000° to 2,000°C) within the airless oven yields the coke byproduct. This device is a crucial part of the cokemaking process. Coke is a solid remainder of ...

Coke is an essential input for the ironmaking process. For making coke, coal is heated in the absence of air to drive volatile matter (VM) from it. Conversion of coal to coke is called coal carbonization and the process is carried out in coke ovens. A coke oven battery consists of a number of coke ovens.

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.

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.

Coal traditionally has been a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.
