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%.
Claims17
A system for melting iron, the system comprising:
- a cupola furnace including a refractory-lined elongate furnace body configured to support coke and iron, and a wind box configured to provide a source of oxygen to the furnace body, wherein the furnace body includes (i) an inlet opening configured to receive the coke and iron, (ii) an outlet configured to provide molten iron;
- a drying region, and (iii) a reaction region downstream of the drying region, wherein, in operation, the cupola furnace is configured to melt the iron to form, at the outlet of the furnace body, the molten iron having a carbon content higher than a carbon content of the received iron;
- and
- a population of coke products disposed within the furnace body at the drying region and the reaction region, wherein individual coke products comprise (i) an elongate shape including a length:width dimension of at least 1.5:1, (ii) an ash fusion temperature no more than 2400° F., and (iii) a coke reactivity index (CRI) of at least 30%.
