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.

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...

Presentation by AlzChem at the AISTECH conference 16.-19.05.2016 in Pittsburgh/USA: "A new method for inclusion modification using calcium carbide". The presentation covers the properties of calcium carbide in comparison to other Ca-carriers and reports on an extensive application study in the steel plant of voestalpine. It has been proven in the steel plant that calcium carbide cored wire is a powerful and safe product for calcium treatment, both for the replacement of other Ca-carriers...

Since the beginning of November last year the new railroad cars have been rolling on tracks across the world, bringing customers CaD – AlzChem's hot metal desulfurization agent. As market leader in the segment of calcium carbide-based hot metal desulfurization agents our job is to ensure rock-solid reliability of supply and punctuality of delivery. The data from the GPS tracker help locate and track our railroad cars. But even more importantly perhaps, the data are used as a valuable input...
