Embodiment 1
[0045]like figure 1 As shown, the present embodiment provides a method for melting vanadium flakes, comprising the following steps:
[0046] Step 1, heating the melting chamber 10,
[0047] The alternating magnetic field generated by the induction coil 13 of the electromagnetic heating device heats the melting chamber 10 to a temperature of 700°C-1000°C;
[0048] Step 2, unloading,
[0049] Conveying the vanadium pentoxide powder into the melting chamber 10;
[0050] Step three, melting,
[0051] Under the situation that the electromagnetic heating device keeps the melting temperature in the melting chamber 10 and the oxygen feeding device of the melting chamber 10 supplies oxygen, vanadium pentoxide melts in the melting chamber 10,
[0052] Step 4, discharge,
[0053] Vanadium pentoxide is discharged through the discharge port 2 of the melting chamber 10 after melting.
[0054] A method for making vanadium flakes is also provided, the method is that the melted vanadium ...
