  • Iron Ore Sinter an overview | ScienceDirect Topics

    Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process Iron ore is typically characterized chemically, physically, and mineralogically TheThe coke and ironore bearing burden (lump ore, sinter and pellets) along with flux materials are fed from the top until the BF is filled with alternating layers of coke and ore at the level of the stockline at the bottom of the throat Compressed hot blast air (1000 – 1300 °C) containing oxygen, nitrogen and moisture, along with additional enriching pure oxygen and pulverized coal is blownOre Sinter an overview | ScienceDirect Topics· Fig 1 Iron ore sinter Types of sinter Sinters are classified into acid sinter, selffluxing sinter, and super fluxed sinter Selffluxing sinter has sufficient content of CaO (lime) in it which is required to flux its acid components (SiO2, and Al2O3) Superfluxed sinter has additional content of CaO for fluxing of the acid components introduced in the blast furnace through other burdenThe Sintering Process of Iron Ore Fines – IspatGuru

  • Sintering: A Step Between Mining Iron Ore and Steelmaking

    · World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process Sinter is the primary feed material for making iron and steel in a blast furnace· Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (eg mill scale, blast furnace dust, and returned sinter fines etc) are converted into a particular form of agglomerate It consists of heating the sinter mix with a particle size of less than 10 mm toTheory and Practice of Sintering of Iron ore – IspatGuruThe coke and ironore bearing burden (lump ore, sinter and pellets) along with flux materials are fed from the top until the BF is filled with alternating layers of coke and ore at the level of the stockline at the bottom of the throat Compressed hot blast air (1000 – 1300 °C) containing oxygen, nitrogen and moisture, along with additional enriching pure oxygen and pulverized coal is blownOre Sinter an overview | ScienceDirect Topics

  • Characteristics Evaluation and High Effective Utilization

    · Iron ore sinter is the major component of blast furnace feed in Asian iron and steel companies, and as a result, sinter quality directly influences the performance of the blast furnace The productivity and quality of sinter are strongly determined by the iron ores used in sintering However, with the rapid development of the steel industry in China, the iron ore resources of good quality areMagnetite in iron ore sinter is usually distinctly different in morphology and reflectivity from phases such as hematite and the SFCA types Sometimes however, if the magnetite contains appreciable amounts of solid solution impurities such as Mg, Ca, Al and Si, the magnetite reflectivity changes and it becomes difficult to accurately distinguish it from SFCA with simple thresholding, ieAutomated Optical Image Analysis of Iron Ore SinterDuring iron ore sintering, a packed bed of uniformly distributed granules—composed of a range of iron ore types, fluxes, fuel, return sinter fines and plant dusts—is transformed into porous sintered particles of irregular shape The yield of the sinter machine (ie the percentage sinter acceptable for use in the blast furnace) governs its productivity and is closely dependent on theEffect of Iron Ore Particle Assimilation on Sinter Structure
