Calcium carbide for acetylene production

Acetylene (C2H2) is the world's most efficient and hottest burning standard welding gas. For producing acetylene, the reaction of calcium carbide (CaC2) with water (H2O) is used, whereas acetylene and lime milk (Ca(OH)2) is generated.   CaC2 + 2 H2O --> C2H2 + Ca(OH)2   For this simple and proven process, AlzChem's calcium carbide is used for more than a century. Calcium carbide is of strategic value for AlzChem, as it is the basis of the NCN-chain. Originating...

Clean steel with CalciPro®

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...
