✦ Synopsis

A mathematical model to predict the strength of a coke manufactured from a blend of coals is proposed. The model operates in terms of 'bond strengths' between the constituents. The magnitudes of these bond strengths may be determined from the strengths of cokes manufactured from the individual constituents and from a limited number of binary blends. The model has been applied to predictions of the M,c index of coke strength for binary and ternary blends, and the predictions are in reasonable agreement with the experimental data. In particular, the model is able to account for the behaviour of incompatible coals and bridging coals in blends.

Mathematical models are proposed to predict the true density of coal, semi-coke and coke and the porosity of a coke oven charge during carbonization. These models are combined in a further model which predicts the hitherto unexplained 'twin-peaked' contraction curve observed for semi-coke. It is fou
