Behavior of pore and bond formation in sintercake on iron ore sintering has been studied by means of computer simulation in which melt flow phenomenon is taken into account. Simulations have revealed that pore size increases with increasing coke content and increasing melt fluidity. On the other hand, the excess of them results in a huge void and dense and massive clusters below which an unfired region is formed. These results are confirmed by comparing with the direct observation by X-ray CT.
