One of the main applications of Calcium Carbide is the production of acetylene gas.

 

CaC2(s) + 2H2O(l) -> C2H2(g) + Ca(OH)2(s)

 

Besides its use as a major chemical building block, acetylene is the hottest burning fuel gas and consumes the least amount of oxygen for complete combustion.

 

C2H2(g) + 2,5O2(g) -> 2CO2(g) + H2O(g)

 

The combustion produces a flame temperature of over 3300°C and releases 11.8 kJ/g.

Alzchem provides Calcium Carbide in the right granulation and with low impurities. A sophisticated supply chain with exchangeable containers transported on rail, truck or ship ensures highest delivery safety.

In the global market the requirements for steel quality are increasing continuously. One of the most important parameters is the cleanliness, which describes the number and size of nonmetallic inclusions in the material. The cored wire CalciPro®, based on Calcium Carbide, is applied in secondary metallurgy to improve the cleanliness. It provides calcium, which modifies the existing oxide and sulfide inclusions in the steel melt and improves castability. The formation, control and effect of...

CaD® is a powerful desulfurization agent based on fine calcium carbide (CaC2) powder. It is available in different grades, which consist of calcium carbide mixed with various supplements. As an example volatile coal powder increases both efficiency and reaction rate. Other additives can optimize slag properties and reduce iron losses. AlzChem produces special CaD® mixtures tailored to the individual requirements of the steel producers.   In the production of high quality steel,...

AlzChem is the only REACH registered producer of calcium cyanamide. Starting from June 2018 only AlzChem is allowed to distribute Calzot® (CaCN2) in Europe. Calzot® is based on the chemical compound calcium cyanamide (CaCN2) and is applied in metallurgical processes. The main use of Calzot® is for nitriding liquid steel by addition of Calzot® in lumpy form or as a cored wire. The nitrogen dissolves in the melt and contributes to an increase in both strength and corrosion resistance of the...

AlzChem introduced CalciPro®, a cored wire based on Calcium Carbide, in the market, which is used for Calcium treatment in secondary metallurgy. It converts alumina inclusions into calcium aluminates to prevent clogging with high efficiency and hence reliably improves castability. Moreover, it is an excellent solution to modify inclusions in order to enhance steel properties such as machinability. The cored wire is packed in a container which guarantees highest safety in transport, storage...
