The new process of dry lining is performed, and the wet laying process of gypsum is eliminated to reduce the moisture of the inner lining, avoid the formation of high temperature steam pressure at the start of roasting, and expand the expansive force of the carbon block and the cold mash. Extend the roasting time of day and night, increase the roasting quality, reduce the temperature gradient of the carbon block, and make the temperature of the electrolyzer close to the temperature during normal production. To avoid a sharp rise in tank temperature at start-up, the lining material, particularly the carbon block, is subject to a strong thermal shock and rapid expansion occurs. During the firing period, the voltage is forbidden to increase, liquid electrolyte is forbidden to form, and the selection and absorption of sodium ions and formation of sodium and sodium compounds by the carbon material at low temperature are delayed, and the delamination of the bottom carbon block at the late start-up period is prevented, resulting in early damage. Strengthen the start-up and start-up management of the electrolyzer, strictly follow the roasting start-up procedure, scientifically manage the electrolyte temperature, liquid aluminum and electrolyte level, effect coefficient, working voltage, electrolyte composition, furnace shape and processing system in the later start-up period. After the start of the electrolyzer into a smooth normal production operation state. The quality of furnace construction materials, especially the quality of carbon block and cold paste, is an important factor affecting the life of the electrolytic cell, and it is also an important cause of early damage of the electrolytic cell. The tank shell is highly deformed and if it does not take corresponding measures, it is also one of the important reasons for early damage of the electrolytic tank. The improper construction technology of the furnace construction, such as wet laid masonry lining of gypsum, will cause hidden dangers for the early damage of the electrolytic cell due to the high moisture content of the inner lining. The phenomenon of desertification and anti-slurry during the process of cold heading and solidification, as well as the phenomena of excessive enthalpy and skipping, all seriously affect the life of the tank and are prone to early damage. The roasting, start-up and later management of the electrolyzers are crucial to the influence of the age of the tanks, so that the electrolysis production will benefit for a lifetime.
