Abstract
The fundamental pore formation mechanism in iron ore sinter and pellets was investigated, using iron ore/limestone tablets with and without addition of coke. The results showed that pores were formed at the sites of limestone and coke particles, and that the particle size and amount of limestone and coke particle size all had strong effect on the pore structure. Different types of pores in sinter and pellets were classified in terms of their origins. These results are useful in understanding the sintering and pelletizing process.
