Results of a Performance Test of Making a Colloidal Anode Mass for a Soderberg Anode

摘要

The results of putting a fundamentally new type of anode mass with a decreased (from 28 to 24%) content of coal-tar pitch and an increased content of the dust fraction of petroleum coke into industrial use are presented. This approach improves the environmental conditions in the works and increases the economic indices of the electrolysis technology of aluminum. A layout of a shop for making the anode mass for the Soderberg colloidal anode is described. The properties of pitch and coke are investigated, and the quality of the produced anode mass is evaluated. The results of a performance test allow one to speak about the com-petitiveness of the electrolysis technology of aluminum with the Soderberg anode.
