Embodiment 1
[0036] Use a crucible furnace to melt the extra sponge titanium (titanium content 99.8%) in vacuum, and raise the temperature to 1700°C; use an induction furnace to melt pure iron ([C]+[Si]+[Mn]+[P ]+[S]+[Al]+[V]+[Ti]3 / (min·t), the argon blowing time is 10min; after the homogenization is completed, the ferro-titanium alloy solution is plate-cast under vacuum conditions, and the ferro-titanium alloy is crushed and packaged after the alloy is cooled to 100°C or below. The Ti content in the obtained ferro-titanium alloy is 29.87%, and the total content of other elements except iron is less than 0.5%.
Embodiment 2
[0038] The titanium shavings (titanium content 99.5%) were melted in an Ar gas protection atmosphere by using a resistance furnace, and the temperature was raised to 1690 °C; the pure molten iron was heated to 1700 °C by a resistance furnace in an Ar gas protection atmosphere (the [C ]+[Si]+[Mn]+[P]+[S]+[Al]+[V]+[Ti]3 / (min·t), the argon blowing time is 3min; after the homogenization is completed, the ferro-titanium alloy solution is plate-cast under vacuum conditions, and the ferro-titanium alloy is broken and packaged after the alloy is cooled to 100°C or below. The Ti content in the obtained ferro-titanium alloy is 69.79%, and the total content of other elements except iron is less than 0.4%.
Embodiment 3
[0040] Titanium chips (titanium content 99.9%) are melted in a vacuum by a resistance furnace, and the temperature is raised to 1695°C; pure iron powder ([C]+[Si]+[Mn]+[P] +[S]+[Al]+[V]+[Ti]<1%) melted and heated to 1700°C after melting; the weight ratio of iron source and titanium source is 5:5, after the two raw materials are heated to the predetermined After heating, under vacuum conditions, the molten iron source and titanium source are hedged and mixed into the red hot alloy ladle, and the composition is homogenized and impurity is controlled by blowing argon gas at the bottom of the ladle, and the argon strength is provided. The temperature is 0.25m3 / (min·t), and the argon blowing time is 15 minutes; after the homogenization is completed, the ferro-titanium alloy solution is plate-cast under vacuum conditions, and the ferro-titanium alloy is crushed and packaged after the alloy is cooled to 100°C or below. The Ti content in the obtained ferro-titanium alloy is 49.81%, an...
