The lime necessary for the production of carbide is admitted to the furnaces in the form of calcium oxide (CaO) which is made separately either by subjecting limestone (calcium carbonate, CaCO 3) to combustion (decarbonization) or by dehydrating lime hydrate (calcium hydroxide Ca(OH) 2) obtained by carbide gasification. The dehydration may be

At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. Generally speaking, the different grades of carbide that we make correspond to different reactivities of the carbide. For example, we produce fast-acting carbide powder that is injected into molten iron to combine with and remove sulfur.
