How does coke and coal play into steel making? FedSteel

Jun 22, 2016 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.

More

Steel Production American Iron and Steel Institute

Coal is a key part of the coke-making 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.

How much hydrogen will be needed to replace coal in making

New plants use less coal than ones that are fifty years old. But the processes employed today will always need very large amounts of coal.[1] Each tonne of ‘new’ steel typically requires about 0.77 tonnes of coal, meaning that the industry as a whole uses just over 1 billion tonnes a year.

Decarbonization in steel McKinsey

While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.

Steelmaking CO2 carbon dioxide emissions by process step

DRI-based EAF plants emit approx. 2-3 tonnes CO2 per tonne of steel if they are coal based, or 0.7-1.2 tonnes/tonne if they are gas-based. Direct emissions from scrap based EAF plants are mostly indirect –the CO2 emissions are not produced by the steel plant, but by the electricity generators that supply electricity to the furnaces.

How a Coke Plant Works GASP

Oct 04, 2018 Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first. Coke is used as fuel in a blast furnace.
