Dec 18, 2018 As a promising method to strengthen the blast furnace smelting and to realize reduced fuel operation, high-proportion pellet charging has become the practice of BF ironmaking. Use of pellet gives rise to uniform bed permeability in comparison with iron ore or sinter. This leads to better gas–solid contact resulting in higher productivity at reduced coke and fuel rate.
