Аннотация: Anode paste for aluminum reduction cells represents a composite material consisting of calcined coke and coal tar pitch. A coke aggregate mix includes 3 to 7 fractions with a particles size of 12 mm down to 63 µm, and even less. Grain fractions larger than 0.2 mm are prepared by crushing and screening. Grain fractions form a sort oПоказать полностьюf skeleton, which makes the aggregate more stable. For filling the space between the grains, a dust fraction with particles less than 0.2 mm is used. The dust fraction comprises up to 50% of the aggregate and can contain up to 75% of particles with a size of
