Abstract：In order to predict, improve and regulate the thermal properties of coke in accordance with the demands, and also to make clear the effect of various factors on the thermal properties, prediction models of coke thermal properties were proposed on the basis of analysis of influence rules of the various factors and by means of ninety six runs of test for sixteen blending schemes, using bulk density (d), coalification degree index (Vdaf), caking property indices (G and Y) and mineral catalytic index (MCI) as input variables. The models simultaneously concern the two kinds of coke making processes, i.e. coal top-charging and coal side-charging, reveal intrinsic rules of influencing coke thermal properties by various factors, determine the optimal value of various factors and the best attainable value of coke thermal properties. The models make prediction with higher accuracies, apply to wider areas, and could be used not only to the traditional coke making process but also to the tamping coke making process. The impact of various factors, ways to improve coke thermal properties and the method of ferro-coke development were also analyzed.
