Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 percent of the total coke production is dedicated to blast furnace operations. Foundry coke comprises most of the balance and is used by foundries in furnaces for melting metal and in the preparation of molds.
The charged coal is heated through the two side walls, so the coal nearest to the walls is heated rapidly and transformed into coke. During the process, the heat that is supplied from gasburning flues located within the walls of each oven is gradually transmitted from the hot brick walls toward the center of the oven charge (Fig. ).
