Electrode Paste:
The petroleum coke and the asphalt are dehydrated and melted in the melting tank, and are mixed into a kneading pot in proportion, and then calcined. It has the characteristics of low resistivity and is used as a conductive material in electric furnace equipment such as iron alloy 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. Therefore, the consumption speed of the electrode and the calcination speed are the key to the use of the electrode paste. As the ore furnace technology gradually develops toward large-scale and air-tight-ness, the electrode develops from the open furnace type to the closed furnace type during the calcining process, and the heat obtained by the electrode from the furnace is greatly reduced, which requires an increase in the sintering properties of the electrode paste to compensate for this deficiency.
