Introduction of Carbon Electrode Paste
The electrode paste made by Rongxing Group 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. Therefore, 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.
Carbon Electrode Paste is produced by putting Calcined petroleum coke, ECA, anode scraps and asphalt into melting tank to dehydration, melt, then adding them into kneading pot to kneading, molding and sintering.
Product characteristics:
1. Lower ash content;
2. Acurate dosing and stable volatile content;
3. Good electric and thermal conductivity and the sintering speed apropriate to that of consumption of working end;
4. Smelting at lower temperature with certain fluidity and homogeneous composition;
5. High resistance to high temperature, oxidation and thermal shock, low resistivity and high mechanical strength after sintering.
