coking coal

- Jun 26, 2018 -

Coking coal , also known as metallurgical coal, also known as the main coking coal.

Coking coal is medium metamorphic bituminous coal. Romax is 1.35%. Because of its strong bonding ability, it can produce high quality coke, which has high strength, large lump size, high strength and few cracks. It is the best raw material for coking.

Coking coal has small shrinkage and high expansion pressure when it is coking alone. It is not easy to be released from coke oven, and it is easy to damage coke oven. So coking coal, fat coal or lean coal must be added to coking coal, so as to improve the operating conditions, improve the quality of coke and expand coking coal resources.
