Application
1.Acetylene Generation :The calcium carbide is sometimes used directly as a processing materials,its main use is obtained when the store react with water to produce acetylene gas;
2.Metallurgical used De-sulphurizer :Calcium carbide is powerful and effective reducing agent .In the metallurgical field ,it is added to liquid iron to remove sulfur impurities before process in the steelworks.
3.De-oxidization :Carbide with size 5-30mm is usually used as de -oxidization agent ;
4.Other Application:Calcium carbide is also a raw materials in the chemical industry .For example in obtaining PVC;
