I can only guess Sir, because have experience with high TiO2 (and even less than 4% TiO2) pellets of BF grade in BF: my pellets are about - SiO2 4,2 CaO 1,2 Al2O3 2,6 MgO 2,4 Fe 60,7 FeO 3,1 MnO 0,2 TiO2 2,9 S 0,002.

In my opinion, the only way to solve your problem will be playing with microfluxing pellets - try to play (of course in labaratory first) with microadditions (like 0,1 - 0,3 %) of CaO and/or MgO.

Thank you so much

We tried with different concentration of dolomite addition which increase the fines generation in the pellet reduction process. Thanks for your reply sir.

Now you can reject limestone and dolomite for this purpose. Now use pure Mg. MgCO3 or Mg(OH)2 for microfluxing

Thank you... is there any idea about the dosing for green ball preparation?

Our Raw material contains, SiO2- 2.5%, TiO2- 3.9%, Al2O3-3.5%, V2O5-1.1%, CaO - 0.35%.. pls suggest me a dosage of MgCO3 or any other solutions if you have. thank you

I recomend to start with 1% of MgO in calcinated pellets - if it works try 0,5% of MgO in calcinated pellets to pay less for fluxes.

According to stechiometry to get about 1% of MgO content in calcinated pellets you add 20 kg of MgCO3 per 1 ton of calcinated pellets burden.

According to stechiometry to get about 1% of MgO content in calcinated pellets you add 15 kg of Mg(OH)2 per 1 ton of calcinated pellets burden.

Mg(OH)2 is better influencing pellet mineralogy according to literature - material is called Brucite.

Also for lab scale experiment you can use pure MgO powder 10 kg of MgO per 1 ton of calcinated pellets burden.

Based on literature MgO is creating solutions with FeO helping to avoid/diminish hematite recristallization with specific wolume increase (swelling = destroy = fines formation) during reduction - change in crystal lattice from α-Fe₂О₃ phase to phase of γ-Fe₂О₃ type during reduction of pellet.

thank you.. we will try to make a small trail in the plant production...
