This paper outlines the fundamental techniques of making blast furnace coke in a slot-type coke oven. First it deals with the softening and melting of coking coal particles, then with their expansion and resolidification, and further. with their shrinkage to form coke texture. The paper next describes the state in which coal is carbonized in coke oven chambers, by first explaining how heat is transferred in these chambers and how softening layers develop.The actual process of cokemaking is also explained with reference to blending of charging coals, their preparation and carbonization condition. Paper concludeswith a brief description of some of the latest techniques to utilize nonor poorlycaking coal, which have come to the fore recently on account of the scarcity of high quality coking coals. They are: the briquette-blend coking process, the binder addition process, the coal preheating process, and the form coke process.
