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.
Calcium carbide is the most popular raw material used for the commercial production of acetylene. It is created by mixing lime and coke in a blast furnace.
