The iron oxide FeO content had a significant impact on both the metallurgical properties of sintered ores and the economic indicators of the sintering process Precisely predicting FeO content possessed substantial potential for enhancing the quality of sintered ore and optimizing the sintering process A multi model integrated prediction framework for FeO
Utilization of biomass as a carbon neutral agent is an attractive one for iron ore sintering Sinter pot tests were carried out with using raw biomass and biomass carbonized char It is not good on yield and exhaust gas that raw biomass is used directly as carbon material for iron ore sintering While it is good on the productivity and the
For a long time the research of ore blending based on high temperature properties of iron ore have been commonly conducted [1 2] However the assimilation properties and flow properties of iron ore are mostly evaluated by the minimum assimilation temperature [] and the liquidity index [] which was seldom considered the sintering process information and
Super high bed sintering process is an important development direction of iron ore sintering for its lower emission and higher yield However there is a lack of deep understanding of the uneven quality of super high bed sintering products and the deterioration of reduction disintegration performance the thickening of hearth layer and the reduction in
ABSTRACT In steel industry and in mines a significant amount of ultra fines waste iron oxides and iron ore fines is generated Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources Some of these fines are normally used in sintering practice However sintering has a limitation of accepting ultra fines materials
The Table 4 shows the size distribution of iron ore and coke used Pelletization Schematic of the experimental is presented in A Fig 1 part of dry Noamundi iron ore fines was ground for 18 min utes to 45 μm 56% approx The size distribution and Blaine fineness of it is shown in Table 5 The iron ore fines
Sintering is a process by which a mixture of iron ores fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition quality and granulometry to be
Iron ore sinter plants are energy intensive components of integrated iron and steel production see Table 1 where the iron ore fines <5 mm are converted into larger >5 mm lump sinter cakes with greater gas permeability which are the most important burden materials for iron making in blast furnaces BFs [7] The main process is shown in Fig 2 and described in
It can be seen from Tables 1 and 2 that the blend with high iron grade has a high content of FeO wt % because it consisted of 70 wt % magnetite concentrate and 30 wt % fine ore The coke breeze has high fixed carbon content wt % and low volatile matter content wt % Methods The double layer sintering process is shown in Fig 1
The sintering process begins with preparation of a sinter mixture consisting of iron ore fines fluxes solid fuel called bonding agents in Japan such as coke breeze and return fines from the sinter plant as well as recycled ferruginous materials from downstream iron and steelmaking processes
The global steel industry uses fossil fuels to produce millions of tonnes of iron ore sinter each year Sintering is an energy intensive process that fuses iron ore and flux to produce material that balances a high mechanical strength at a sufficient particle size to ensure a macroporous burden in the blast furnace to enable rapid gas flow As significant CO2
