Technical Calcium Carbide (CaC2) is produced in electric arc furnaces. The chemical reaction between the raw materials, burnt Lime and coke takes place between 2,000 and 2,200°C in the electric arc. The Calcium Carbide is tapped into ingot molds. After cooling, the solidified blocks are crushed and processed. Technical Calcium Carbide consists of approx. 80% CaC2 and mostly CaO. In many cases it is used as the starting product for the production of acetylene, which is chemically processed into polymers or used for welding purposes. In the iron and steel industry calcium carbide serves as a reduction and desulfurization agent. ALMAMET produces calcium carbide powder and mixtures for this key field of application.
