The Roles of Coal and Coke in Steelmaking

Jul 16, 2014 · Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a non-melting carbon. Coke is made by one of two processes: by-product or non-recovery, also known as heat recovery. In by-product coke making, impurities are driven off the coal in order to leave nearly pure carbon.

How is coal formed?

In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite - is the lowest rank of coal - which means that it has the lowest heating value and lowest carbon content. Although lignite is more solid than peat it crumbles when shipped long distances.

Coke is a material with high carbon content and porosity. It has high resistance to breakage and low reactivity with gases, particularly CO2. Coke production is an important part of the integrated iron and steel plants using BF-BOF route, acting as a reducing agent, as a source of thermal energy, and providing physical support for the burden in blast furnace.

Can We Make Steel Without Coal? - Coal Action Network Aotearoa

Apr 24, 2013 · Steel is made in a subsequent process as an alloy of iron and carbon (along with some other elements). Around 1% of the carbon from the coke remains in the raw iron to provide the source of that carbon. So coal (as coke) is a reducing agent, a source of energy to drive the process and a source of carbon to incorporate in the steel.
