Tungsten Alloy Smelting Method

The present invention provides a tungsten alloy smelting methods. Characterized in that:

The charge is heated to a temperature region; then adding a certain amount of tungsten ore concentrates with a reductant and a mixture.

Specific steps are as follows:

1) First, 100-110% the theoretical amount of material added to the steel material or iron in an electric furnace heated to a reaction tank 1540-1590 ℃, melted;

2) Then by mixing the tungsten concentrate, aluminum particles and sodium nitrate mixture to 70-110 kg / min m Speed ​​2 to join the tank; during feeding, continued heating, the furnace temperature was raised to 2500-3000 ℃;

3) After the addition, continue to add heat to the melt, maintaining a temperature above its melting point slag 7-20 minutes;

4) Stop heating the furnace to melt naturally cooled after solid baked.

Tungsten alloy smelting method of the invention has the smelting process short, simple application, low energy consumption, the advantage does not require ignition agent, reducing the amount of provincial and so on.
