Tóm tắt

Investigations performed an anode of the aluminum electrolyzer, showed the nonuniformity of coke particles in regards to the height of the region of the pitch-coke composition. This is associated with the sedimentation of coarse fractions of the coke charge in a viscous medium. The sedimentation of coarse coke particles is investigated in laboratory conditions for the model of liquid pitch-coke composition, and the characteristics of this process are determined. The composition of the coke charge, which provides the sedimentation stability of the anode mass in the region of pitch-coke composition of the Soderberg anode, is suggested.
