 Anode paste is the predecessor of preparing anodes in electrolyzers in aluminum plants. In the 40 years before 1995, the anode paste was once the largest product in China's aluminum carbon products. After 2000, this product will gradually be replaced by anode carbon blocks. It is the product with the largest output among carbon products. The anode paste is a carbon paste made of petroleum coke and pitch coke as aggregates and coal tar pitch as a binder. It is used as anode material for continuous self-baking aluminum electrolytic cell. Because of its high content of binder (more than 24%), it is paste-like before the upper part of the electrolytic cell is sintered, so it is called anode paste. The prepared anode is not only capable of good electrical conductivity, but also resistant to high temperature and corrosion, and at the same time the price is low. The resistivity of the preliminary anode is 50-70 μΩ.m, plus the lead and contact resistance, during normal aluminum electrolys

 The following points should be paid attention to when installing the electrode paste airtight paste: 1. Do not allow debris to enter the electrode 2. Proper paste height 3. Work harder 4. Appropriate temperature 5. Prevent overhang Before filling, the electrode paste should be broken, generally broken into small pieces of 80~100mm, so that the electrode paste block can pass between the two ribs smoothly. If the particle size is too large, the electrode paste suspension failure is likely to occur; if the particle size is too small, it is easy to cause the phenomenon of spraying. Use a forklift truck or special tools to transport the electrode paste to the calcium carbide furnace, and use an electric hoist to hoist the electrode paste into the electrode bucket. Pay attention to the safety of hoisting during loading. When installing electrode paste, be careful not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid accidents of electric fire. Ever
