| Abstract: | With the increase of the amount of high Al2O3 iron ore used in the blast furnace, Al2O3 content in the blast furnace slag inevitably increased. The discussions on the relevant measures for the blast furnace smelting of iron ore with high Al2O3 content, status of high Al2O3 operation in China, and especially proper w(MgO)/w( Al2O3) ratio were conducted deeply based on a complete review of the minus effects of Al2O3 on sinter process, metallurgy properties of sinter, and blast furnace smelting. |
