foundry coke

Foundry coke is a specific type of coke, a solid residue produced by heating certain coals at high temperatures without air. This process, called carbonization, drives off volatile components, leaving behind primarily carbon with small amounts of other elements and the coal's mineral matter.1

Foundry coke is characterized by its large size and strength, making it ideal for use in foundry cupolas to melt iron ores. Other sizes of coke have different applications, such as in blast furnaces for iron production, in metallurgical processes, or as fuel. The carbonization process also yields by-products like tar, ammonia, and gases that can be used as fuel.123
