文摘The variation regularity of coke strength was investigated in terms of the genetic factors and petrographic parameters of coal in collaboration with the technical properties of coal. A concept of inert holding ratio of coal was proposed. There is an optimal inert holding ratio for different ranks of coals for making coke with highest combined strength. The additive property of inert holding ratio under normal conditions was demonstrated with actual examples of coal blending.Thus it is possible to predict the combined strength of coke through reflectance, content of inert components and caking index diagram system.
