Calcium Carbide Applications
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.
