Sinter Reduction First, the relation between straight lime basic sinter's susceptibility to disintegration and basicity was examined under various boundary conditions. Some selected results are shown in Figure 2: for variable fuel rates disintegration is governed by various influence factors: first, there is the wellknown maximum as a function of basicity.

This is similar to the porosity values of the commercial lump iron ores used in the blast furnace (% for MBR Brazil iron ore) and the direct reduction processes (–% for Orissa India iron ores) . Furthermore, sample Ug5, whose chemical composition is similar to that of samples Ug14 had a higher porosity value of %.

Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Sinter strength plays an important role in deciding PCI rate in the blast furnaces.

dingly. Iron ore is being used for iron and steel production. It is being used in two forms, lump and fines. The lump is used directly in the blast furnace or for direct reduction in alternative ironmaking processes. The fines are used as agglomerates (sinter/pellet) after some more preparation.

The Outotec AusIron process is capable of producing hot metal from a variety of ironbearing materials while using locally available coal in a single reactor. Allows iron ore fines to be processed without the need for agglomeration processes such as pelletizing or sintering ; Offers high flexibility for iron feedstocks and coal grades

'For decades, steelmakers have used highly polluting ovens to turn powdery coal and iron ore into chunks called coke and sinter, which are melted with superheated air to make iron.' 'The increased sinter burden is also expected to enhance the productivity of blast furnaces, effecting a substantial reduction in the cost of sinter ...

May 17, 2017· Goethite has relatively high reactivity during sintering leading to greater melt formation and assimilation. BF feed is now dominated by sinter (up to 85%) compared to traditional lump. Goethite lump has good reducibility, but some susceptibility to reduction degradation. Decrepitation can be a problem in dense, goethitebearing ore types. Water
