Because of high alkaline earth metal content, the reduction swelling of Baotou pellet makes blast furnace operation very difficult. A series of experimets with Peru ore and Baotou pellets were performed. The influences of various factors on pellet swelling and of K_2O on iron ore swelling were studied. The results show that when K_2O increases to 1%, the swelling ratio rises from 7.3% to 30.19%.
