Abstract

Disclosed herein are methods and systems for coking coal blends to produce a foundry coke product. A method for producing a coke product can include charging a coal blend into a coke oven; and heating the charged coal blend such that a crown temperature of the coke oven is above a lower coking temperature. A pyrolysis duration begins when the crown temperature of the oven is above the lower coking temperature and ends when the crown temperature of the oven is below the lower coking temperature.
