【Rongxing Electrode Paste Product】
Rongxing 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.
With the characteristics of low resistivity, it 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.

【Note for Rongxing-made Electrode Paste】
In addition to properly grasping the above two methods, the production of Rongxing 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.
