30+ YEARS OF EXPERIENCE IN CARBON INDUSTRY

Electrode paste (specifically for self-baking electrodes) serves as the raw material for self-baking electrodes in submerged arc furnaces, particularly those used for smelting ferroalloys such as ferrosilicon, silicomanganese, ferrochromium, and silicon-calcium. Utilizing the heat generated within the furnace, the paste inside the shell gradually bakes and solidifies to form a conductive carbonaceous electrode that continuously supplies current to the smelting arc, it is the most widely used electrode consumable in ferroalloy smelting.

Currently, standard electrode paste is typically used in domestic production of ferrosilicon, manganese-based, and chromium-based ferroalloys via submerged arc furnaces. However, with the widespread adoption of large-capacity and enclosed submerged arc furnaces, many furnaces producing silicomanganese are transitioning to closed electrode paste to ensure the self-baking electrodes sinter effectively and promptly. Ferronickel producers, in particular, tend to prioritize high-grade closed electrode paste tailored to their specific operational needs. They favor this type because it bakes easily and offers stable performance and quality.This reliability ensures proper electrode baking and prevents failures such as soft breaks, hard breaks, or electrode tip detachment.

The key to the long-term, stable operation of ferroalloy lies in the proper functioning of the electrode columns.Indeed, electrodes are often regarded as the "heart" of the submerged arc furnace. The central issue is the quality of electrode sintering, which ensures sustained, stable operation and minimizes accidents. In reality, the cost of electrode paste accounts for only a tiny fraction of total
