Metallurgical coal is a special type of coal used to make metallurgical coke. There are two types of metallurgical coal used to make coke: hard coking coal and semisoft coking coal. According to Grande Cache Coal, these types of coal are ideal for coke because they melt, swell and re-solidify when placed into a superheated furnace.
Results show that the crushing strength of coke is improved greatly when the hot pressing is conducted at 420 ℃∼440 ℃ for the 1/3 coking coal.

The differences in coke reactivity could be related to the coke crushing and fissuring. Even though the coke crushing process is standardised and it was previously concluded that coke on 20 mm size scale could be considered homogenous [12] and free of fissures [13], [14], recent research shown that coke crushing introduces micro-fractures …
Gates on the wharf are opened to allow the coke to fall onto a conveyor that carries it to the crushing and screening station. After sizing, coke is sent to the blast furnace or to storage. ...
