Reduction of Iron Ore Pellets, Sinter, and Lump Ore

2020-3-23  The magnetite in sinter first reduces slowly, yielding a higher reduction rate in pellets at lower temperatures. Gas compositions vary as a function of temperature. When looking at the composition from the perspective of reactive gases (carbon monoxide and hydrogen), the reductive gas amounts increase.

Optimized use of MgO flux in the agglomeration of

2015-4-11  The optimized use of MgO flux in the agglomeration of high-chromium vanadium-titanium magnetite was investigated systematically through sinter and pellet experiments. MgO was added in the form of magnesite. When the content of MgO in the sinter was increased from 1.95wt% to 2.63wt%, the low-temperature reduction degradation index increased from 80.57% to 82.71%.

The balance of TiTanium and vanadium in The blasT

The investigation concerned the use of sinter containing a titanium-vanadium-magnetite concentrate for the production of pig iron. Sinter containing 0,46 to 0,51 % TiO 2 and 0,056 to 0,060 % vanadium was used for pig iron production in the blast furnace. Introducing 200 kg of this concentrate to the1 Mg sinter mix did not cause any ...
