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 ...

Coal to Make Coke and Steel University of Kentucky

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.

In the coking plant, coal is heated in the absence of oxygen to 1250c. This removes any impurities in the coal, resulting in coke, which is a porous substance that is nearly all carbon. To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process.

How to Create Coke in a Coal Pilot Plant or Testing Oven

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 ...

The original blast furnaces at Blists Hill, Madeley In 1709, Abraham Darby I established a cokefired blast furnace to produce cast iron. Coke's superior crushing strength allowed blast furnaces to become taller and larger. The ensuing availability of inexpensive iron was one of the factors leading to the Industrial Revolution.

Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree atmosphere (coked) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes (primarily in blast ...

How does coke and coal play into steel making?

How does coke and coal play into steel making?

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: A chamber of brick or other heatresistant material in which coal is heated to separate the coal gas, coal water, and tar. The coal gas and coal water fuse together with carbon and the remaining ash, forming a hard residue commonly referred to as coke. Coke is primarily used in steel production. There are two types of coke ovens: (1 ...

However, the January 2016 closure of the Shenango Coke Works coalprocessing plant provided an astonishing example of how quickly those same communities can recover from the most dire impacts of pollution. Shenango was a coke oven — a facility that heats coal to around 2,000 degrees Fahrenheit to produce coke, which is in turn used to make steel.
