Iron ore pellet disintegration mechanism in .

Disintegration of iron ore pellet in simulated shaft furnace conditions was studied. • Pellet disintegrated acutely as reduced by H 2 /CO = 0.8 at 550 °C. • Lattice transition stress and crack generation led to pellet structure failure. • SiO 2 or CaO could remarkably lower reduction disintegration index of pellet.
