In recent years, the blast furnace as a manufacturing process of steel material is in use. The coke is indispensable to obtain iron in the furnace. Each blast furnace company has been improving the structure and composition of the coke material for energy-saving and environmental conformity in iron production. The coke is used for the purpose of supply of the thermal energy by combustion and maintenance of the breathability in a furnace. In order to maintain the breathabiliy against sever loading condition in a blast furnace, high porosity and strength are required for the coke. In this research, the computational model simulating the coke is proposed using three-dimensional finite-element model considering its porosity. By using the model, the material properties of coke, that is the young's modulus, Poisson's ratio and compressive strength, are calculated and these values are discussed with the percolation factor of pore in the coke.
