Progress of Iron Ore Sintering Technology

The quality of the sinter influences its behavior in the blast furnace and the technical parameters of the blast furnace.The quality and the properties of the sinter are mainly determined by the properties of the iron ore powder.In recent years,the iron and steel industry faces with increasing cost pressures,as the quality of the powder iron ore deteriorates and its price increases.Meanwhile,an important progress is made in the technology of the iron ore sintering,especially in the development of the temperature sinter and high-depth sinter,the improvement of limonite technology,the design of pre-reduction sintering and Mosaic Embedding Iron Ore Sintering(MEBIOS),and the improvement of temperature properties of iron ore sintering,which will be briefly reviewed in the present paper.These technologies are aimed for more efficient use of the iron ore powder resource,related with concerns for resource degradation and environmental deterioration.The quality of ore is only a relative concept-a low quality ore can become relatively high if its strengths are exploited and weaknesses suppressed.These new technologies can reduce the consumption of ore and improve the quality of the final product,which are characteristic of a good ore,which means the efficient use of inferior resources.
