Abstract The high temperature compression strength of coke was studied using a high temperature compression testing machine with adjustable atmosphere. In the scope of real reactions in blast furnace, the compression strength of coke is in a linear relationship with its carbon loss rate LC. The influence of LC on the strength is reduced with the increase temperature. The relationship between the compression strength and temperature could also be described by straight line. The integrated influence of the temperature and LC on coke strength and change of coke strength in blast furnace are discussed. It was proved that the compression strength of coke can be decreased by over 70% outside the combustion zone in blast furnace.
