Characterisation of iron ore sinter products with varying binary
Iron ore sinter is one of most extensively utilised ferrous burdens for blast furnace (BF) worldwide. The sinter quality greatly depends on the microstructure and chemical compositions of calcium ferrites which is significantly affected by sinter basicity (mass ratio of CaO to SiO 2).The characterisation of iron ore sinter products with varying binary basicity …
