Abstract
Foundry coke products, and associated methods and systems for melting iron in a cupola furnace with the coke products are disclosed herein. A representative method can include receiving a population of coke products and iron in a cupola furnace, and melting the iron in the cupola furnace to form molten iron having a carbon content higher than a carbon content of the received iron. The coke products can comprise (i) an elongate shape including a length:width dimension of at least 1.5:1, (ii) an ash fusion temperature of no more than 2400° F., and/or (iii) a coke reactivity index (CRI) of at least 30%.
