Metallurgical Coke - an overview ScienceDirect Topics

The contraction ratio of coke produced from low-rank coal (high-volatile matter coal) is high because its resolidification temperature is low. Because there is a temperature distribution among the coke in the coke oven chamber, the different rates in contraction lead to strains, which cause thermal stress and generate fissures in the coke.
