One of the required properties of coke for blast furnace is it's size to maintaine permeability. Then, authors investigated changes in the size and the tensile strength of coke during a conveyance process, and calculated the size distribution of coke after breakage by using the initial size and the tensile strength of coke. The main results are summarized as follows. (1) Change in size of coke and the effect of positions in the coke oven on coke properties are clarified by the sampling and the simulation of the conveyance process. (2) The tensile strength of coke is analysed by the Weibull's distribution function and the stabilized effect is quantitatively clarified. (3) The calculation of the effect of the initial size and the tensile strength of coke on the size distribution makes it possible to estimate the size of coke charged in blast furnace.
