Аннотация: Specimens from the zone of the coke-pitch composition (CPC) of "dry" and "colloid" Soderberg anodes with pitch contents of 28.2 and 24.0%, respectively, are sampled. The relative elongation coefficient and viscosity of the specimens are measured, and the granulometric composition of the coke charge is determined. It is noted that the properties associated with composition fluidity provide the uniform filling of the anode case even at a lowered pitch content. The redistribution of the coke particles in the CPC zone of the operating electrolyzer is characteristic of the dry anode during the sedimentation of the particles. No such phenomenon is noted for the CPC of the colloid anode. This excludes the possibility of stratification of the anode mass and forms more favorable environmental conditions for the electrolyzer operation.
