In this research, two dimensional and three dimensional model using different parameters to investigation for the shape of the raceway and the raceway hysteresis effect. In result, tuyere length make raceway change depth due to will effect. Tuyere tilted angle will change raceway location, as for height and depth of raceway is effected by the bed height. Tuyere height influences raceway internal fluid. It is shown that bigger shape blast furnace raceway is formed by making use of sorghum particle experiments. It is due to sorghum particle will break by hitting each other and broken particle cause an obstruction for blast furnace raceway porosity. Therefore, blast furnace raceway size is bigger than plastic particle.
