Abstract
Coal blends used to produce foundry coke products are disclosed herein. Coal blends can include first coals having a first volatile matter mass fraction less than or equal to a first threshold, and second coals having a second volatile mass fraction greater than or equal to a second threshold that is less than the second threshold. The coal blend can have an ash fusion temperature less than 2600° F. and an aggregated volatile matter mass fraction between 15% and 25%.
