摘要
Special grade bauxite and roll scale were used as raw materials to investigate the influences of reducing atmosphere and firing temperature on sintering clinker. The results showed that: 1) The mixture of the materials could be sintered enough to synthesise hercynite under reducing atmosphere by adding reducing reagent; 2) The hercynite clinker could be sintered to high density and the content of FeAl 2O 4 may attain 80～90% under the firing temperature of 1550℃.
