Deposition of coke particles in the liquid pitch-coke composition of the soderberg anode
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.
