  • Sintered Ore Philippine Sinter Corporation

    sintering of iron ore is a pre-process vital to steel manufacturing. It begins with the mixing of fine iron ore, solid fuel such as coke breeze & anthracite coal, and flux such as limestone & dolomite. sintered iron ore sintered ore is the result of the sintering process. the product is made of ferrous and calcium which can be produced iron ore sintering is a complex thermo-chemical process and the qualities of sinters being produced affect the blast furnace performances in terms of fuel consumption, smooth operation, and rate of production. presently, the proportion of sinters

  • Calcium Ferrite Formation Characteristic During Iron Ore

    It is generally known that the large formation amount of calcium ferrite is favorable for the iron ore sintering. the effects of sintering temperature and content of inlet gas on the calcium ferrite formation characteristic of typical iron ores, including hematite, limonite, specularite and magnetite, were investigated. and the effect of content on the microstructure of the roasted the sinter. In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. however the goethite and gangue contents are relatively lower than the hematite, but the goethite gangue to hematite ratio influences the reactivity during sintering. the minerals association in iron

  • Ore Blending Ratio Optimisation For Sintering Based On

    the iron ore blend for sintering depends to a great extent on ore properties. It is hard to determine the final sinter reducibility from the reducibility and ratio of single iron ores in a mixture. for production cost reduction, optimised blending ratios were designed according to ore prices and properties (microstructure, crystal water iron ore sintering involves the movement of a flame front down a particulate bed, and a series of phys-ico-chemical reactions over a large temperature range. In the literature simple and more sophisticated iron ore sintering models have been reported. In this paper a

  • A Fundamental Study Of The Cocombustion Of Coke And

    In a global carbon cycle, the net greenhouse gas emissions can be significantly reduced if fossil fuels could be substituted with renewable and cleaner biomass-derived fuels. In the traditional iron ore sintering process, the complete replacement of coke, a coal-derived fuel, with charcoal is not possible because the two fuels have very different properties and combustion behaviors during the iron ore sintering process, two types of particles are present in the sinter bed: fines, which are actively taking part in melting and the formation of secondary phases, and coarse ores, which are partially interacting with the surrounding melt. the quality of the final sinter is particularly determined by the secondary phases and their bonding ability.
