The quality of electrode paste is improved. The physical and chemical indicators of sintered self-baking electrodes and carbon electrodes are getting closer and closer. See Table 3. The raw materials used for carbon electrodes and self-baking electrodes are the same. The formula and the height of the electrode column can also be adjusted to the self-baked electrode. Some indicators even exceed the carbon electrode.
The actual measurement results of the 31500KVA silico-manganese fractured electrode with a diameter of 1.5 meters also prove this point. At present, the domestic high-quality electrode paste has reached or surpassed the foreign index, which can fully meet the requirements of the large-scale ferroalloy submerged arc furnace of Mazu.
