3,calcium carbide applications:

1) the main raw material for producing acetylene gas.

2) cutting and welding for metal material.

3) to synthesize polyvinyl chloride(pvc).

4) fruit catalyst.

4, calcium carbide production process:

the production methods of aerobic hot and heating method. general electric heating method is used more production calcium carbide, namely the quick lime and carbon materials (coke, anthracite or petroleum coke) in calcium carbide furnace, rely on the arc high temperature melting reaction and generate calcium carbide.
