  • Elkem Carbon Solutions Elkem

    Elkem has developed its own production technology for prebaked electrodes. Special raw materials are chosen and electrically calcined to achieve the best properties. Forming and baking of electrodes involves a process with a much shorter lead time compared to traditional prebaked production. This process also makes it possible to make single electrodes with individual properties if a
