Description
Metallurgical coke is an important raw material for pig iron production in the blast furnace. It is produced by destructive distillation of coal in coke ovens without contact with air, a process known as coking.
The coke undergoes severe mechanical, thermal, and chemical stresses during the pig iron production process.
Metallurgical coke is a macroporous carbon material of high strength produced by carbonization of coals or coal blends at temperatures up to 1200°C.
The absence of oxygen in the coke oven is essential for producing high-quality coke.
A coke oven battery consists of a number of ovens built in a row with common walls between neighboring ovens. Coal is introduced from the top to produce an even layer, and carbonization proceeds from top to bottom and is completed in two to three days
