Background
The cathode cold ramming paste for aluminum is a ramming material of cathode carbon blocks with construction temperature of 8-25 ℃. The cold ramming paste can be directly used at room temperature without heating due to the low construction temperature of the cold ramming paste. Therefore, the damage to the body and the pollution to the environment during the construction of workers are obviously improved. Thus, more and more aluminum electrolysis enterprises tend to connect ramming materials between lining carbon blocks, and cold ramming paste is one of the key materials for determining the service life of the electrolytic cell.
The cathode gap between the carbon blocks at the bottom of the aluminum cell and the peripheral gap between the carbon blocks (silicon carbide) and the side wall carbon blocks are connected by filling cathode carbon paste by ramming. The baked cathode carbon paste cokes the lining carbon blocks of the electrolytic cell into a whole. After the carbon block of the lining material of the electrolytic cell is roasted, the ash content, the volatile matter, the heat conductivity, the resistivity, the compressive strength, the sodium permeation resistance and other physical and chemical indexes can meet the industrial requirements, so the weakest part of the lining is an interpolar seam and a peripheral seam. Due to the influence of the performance of the cathode paste, the ramming technology, the construction air pressure, the preheating roasting mode and other factors, the defects of pore cracks, interlayers and the like are difficult to avoid by the carbon seam paste, and high-temperature melt often leaks from the defects of the carbon linings most easily.
