【Introduction of Rongxing Electrode Paste】
The electrode paste is dehydrated and melted by petroleum coke and pitch coke in a melting tank, and proportionally added to the kneading pot and kneaded, then molded and calcined.
It has the characteristics of low resistivity and is used as a conductive material in electric furnace equipment such as ferroalloy furnace and calcium carbide furnace. Electrode paste can be said to be a simple and technically complicated product in carbon production. After being kneaded and molded, the electrode paste became a finished product. Unlike other carbon and graphite products, when defects occur in the previous process, it can be compensated by baking, graphitization or even an impregnation process.
The electrode paste is calcined by the heat in the submerged arc furnace. There- fore, the consumption speed of the electrode and the calcination speed are the key to the use of the electrode paste. As the submerged arc furnace technology gradually develops toward
large-scaled and air-tightness, during the calcining process, the electrode develops from the old type opened furnace type to the closed furnace type, and the heat obtained by the electrode from the furnace is greatly reduced, which requires an increase in the sintering perfromance of the electrode paste to compensate for this deficiency.

【Special Note for Electrode Paste】
For electrode paste manufacturers, the two most taboo problems are soft and hard electrode breakage, of which soft breakage is even more terrible and can easily cause accidents. Hard breaking is caused by insufficient strength of the electrode paste after sintering; soft breaking is because the electrode sintering speed is not as fast as the consumption speed, and the lowering is too fast. The electrode cannot be fully sintered and cannot withstand the tensile and lateral impact of the lower part of the electrode, causing fracture. These two problems are directly related to the performance of the carbon manufacturer's electrode paste, and also related to the operation during use.
At present, the main problem that plagues manufacturers is that the electrode paste baking speed is too slow, so some manufacturers use methods to reduce the amount of asphalt used. This method is effective to a certain extent, but the amount of bitumen is too low, resulting in poor fluidity of the electrode paste, the electrode paste is not easy to fill in the electrode barrel, and the poor density after sintering is easy to cause hard breaks. Another method is to reduce the bitumen The softening point of the electrode increases the sintering speed of the electrode, but the softening point of the asphalt can not be reduced indefinitely, because the too low softening point of the asphalt reduces the coking rate of the asphalt.
Therefore, in addition to properly grasping the above two methods, the production of electrode paste also needs to improve the sintering speed of the electrode through the adjustment of the formula, such as appropriately adding graphite materials with good conductivity and heat transfer performance in the formula Conduction heat obtained in the furnace to speed up the roasting speed, while trying to reduce the consumption of the electrode to reduce the speed of the electrode lowering can also achieve the matching of electrode consumption and roasting.
