[PDF] Iron ore pellet disintegration mechanism in ...

Abstract The disintegration behavior and mechanism of iron ore pellet in simulated shaft furnace conditions were investigated in details. Effects of temperature, reducing gas and gangue compositions were emphatically discussed. It was found that pellet disintegrated acutely as reduced by H2/CO = 0.8 at 550 °C. Gangue minerals in pellet were proved to ease the disintegration in various degrees.
