Vanadium–titanium magnetite ore blend optimization for

Sep 10, 2015The method of V–Ti iron ore blend optimization for sinter strength based on iron ore basic sintering characteristics is useful. (2) The BSCs of 5 kinds of V–Ti ores DB, HW, YT, JL and FH are good except LF. (3) The key reason that V–Ti sinter with a poor TI is the low LF, which caused the sinter with a large-pore structure.

IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingIron is one of the most important metals in mechanical engineering, as it is present in sufficient quantities on earth. The extraction of iron can therefore be very economical. However, pure iron is not suitable for use as a construction material. It is much too soft in its pure form and has too little strength to meet most mechanical requirements. For this reason, it is necessary to use alloying additives to give the iron its hardness and strength. It has been shown that carbon is an excelle

Iron Ore Sinter an overview ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.

Fundamental investigations of differences in bonding

Sinter made from magnetite concentrates (<10% hematite) relies on the formation of a network of fused magnetite–magnetite grains (diffusional bonding) and high temperatures (1350–1370 °C) to obtain satisfactory sinter tumble strength. Magnetite–hematite concentrate mixtures, with <45% hematite, behave during sintering like magnetite

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.

The influence of MgO addition on sinter mineralogy was studied on sinters produced in a laboratory installation, with a wide range of MgO/CaO ratios at several basicity indices [B = (CaO + MgO)/ (SiO2 + A12O3)] between 0.7 to 1.9. The most striking influence of MgO is the suppression of hematite and Ca-ferrite phases and the increase in magnetite phase.
