We have herewith some discussion on the two main problems for coke ; (A) the principal qualities of coke that affect its behaviour in blast furnaces and (B) the specification to blast furnace coke. In the first, some chemical qualities of coke are briefly touched upon and for its physical qualities, many examples of coke in our Government Steel Works are quoted. Among many qualities of coke, hardness and abradability have been considered as most importance for blast furnace use. coke used in our Works for many years has generally been considered as too friable for such big plants as 500 or 1, 000 tons furnaces, but from our recent tests and comparison of them with European and American data, it is found that the hardness and abradability of our coke are not necessarily unfit for big furnaces. Knowledge of those properties of coke that are of importance in blast furnace practice would naturally lead to define its specification. We, therefore, suggest that it would give encouragement to manufacturers and reflection to users to place a momentary value on each of the important properties of coke. In determining specification, however, it is necessary to take the local condition into account. This would do much for both the cock manufacturers and its users.
