TITANIUM IN THE PROCESS OF SMELTING PIG IRON WITH AN ...

The share of 200 kg titanium-magnetite concentrate in the sintering mixture allowed a sinter of the contents of 0.48 % TiO 2 and 0.059 % V to be obtained. The introduction of titanium-magnetite concentrate to the production of sinter caused a reduction of sintering belt output by about 4 % with an increase in quick coke consumption by about 5 %.

Developing the Oxidation Kinetic Model for Magnetite Pellet

1073 K (300 C to 800 C)) and sintering at higher temperatures (>1273 K (1000 C)).[1,2] Ideally, it is desirable to have complete oxidation before the start of sintering to achieve best pellet properties.[2,3] When a partially oxidized pellet consist-ing of a hematite shell and magnetite core begins to sinter, complete oxidation may not occur.

Sintering: A Step Between Mining Iron Ore and Steelmaking

Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel.
