The electric energy of submerged arc furnace to produce ferronickel is mainly transmitted through self-baked electrodes. The working quality of self-baked electrodes is closely related to the quality of electrode paste. Most domestic enterprises that produce nickel pig iron in submerged arc furnaces are using Rongxin Carbon Products Co., Ltd.’s high-standard sealed paste, and most of them have achieved stable production operations. The company is a technology-based enterprise integrating R&D, production and sales of special airtight pastes. As the output of nickel pig iron continues to grow, because it can effectively meet the production needs of ferronickel electric furnaces, it is cordially referred to by many nickel pig iron enterprises as “high-standard sealed paste for ferronickel electric furnaces.”
Authoritative experts evaluated the special airtight paste “low ash content, high strength, low specific resistance, good electrical and thermal conductivity, good resistance to rapid cold and heat, and effective, based on the research results tracked during the smelting of ferronickel in the 33000k VA submerged arc furnace. It can prevent the electrode from cracking, oxidizing honeycombs and falling off. The furnace condition is stable and there are few accidents. The electrode paste consumption per ton of iron is about ten grams, which saves cost compared with the standard paste. The user is very satisfied.
