METHOD OF ANODE PASTE PREPARATION TO FORM UNTREATED ANODES Russian patent published in 2014 - IPC C25C3/12 

FIELD: electricity.

SUBSTANCE: method includes preparation of coke grain and dust fractions, adjustment of particle-size distribution for coke fractions, heating of the mixture and its mixing with pitch binder, cooling of the received anode paste, forming of untreated anodes. During preparation of the mixture particle-size of coke dust fractions is adjusted by determination of their total specific surface area, calculation of deviations from the preset value of total specific surface area, calculation of correction value and time for corrections, correction is made against the preset value of total specific surface area and correction is made for dosing of coke dust fractions, upon formation of an untreated anode its apparent density is determined and correction of pitch-binder dosing is made depending on the value and sign of the deviation from the present apparent density for untreated anodes. All corrections are made in online mode.

EFFECT: improving quality of untreated anodes and service life of annealed anodes.
