metallurgical coke

https://doi.org/10.1351/goldbook.M03866
Metallurgical coke is produced by carbonization of coals or coal blends at temperatures up to 1400 K to produce a macroporous carbon material of high strength and relatively large lump size.
Note:
Metallurgical cokes must have a high strength to support heavy loads in the blast furnace without disintegration. Metallurgical @C01142@ is also used as @F02364@ for @P04730@ products.
