Effect of K₂TiF₆ on Fe reduction in the process of magnesium smelting

The thermodynamic feasibility of Potassium hexafluorotitanate (K₂TiF₆) on Fe reduction was calculated in the process of magnesium smelting. The influence factors of Fe reduction, such as the way, content, temperature of K₂TiF₆ being added and the holding time were studied and discussed. The experimental results showed that reducing MgO in magnesium melt and enhancing the temperature can improve the effect of reducing Fe using K₂TiF₆. The content of Fe in magnesium melt can be reduced from 0.028% to 0.004% when it is added 0.3%~0.4% K₂TiF₆ which is counted by pure titanium to magnesium melt, and the temperature is 780°C, holding time 20 min respectively.
