The balance of TiTanium and vanadium in The blasT

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 ...
