PROCESS OF PREPARATION OF ELECTRODE COKE FOR PRODUCTION OF ANODE MASS Russian patent published in 2002 - IPC

FIELD: production of anode mass for self-baking anodes of aluminum electrolyzers. SUBSTANCE: process makes it feasible to raise technical and economic index of operation of anode mass shop and electrolysis shop and to widen feedstock base of production of anode mass since it is possible to process jointly cokes of various origin and of different physical and chemical properties, specifically, of unspecified degree of thermal preparation by suppliers in calcination furnace equipped with cooler. Mass relation of coke from calcination furnace to calcinated coke from storage depot is kept in bounds 1-4:1. For realization of this process it will necessary to organized separate acceptance and storage of calcinated and uncalcinated cokes at storage depot. EFFECT: raised technical and economic index of operation of anode mass and electrolysis shops. 2 cl, 3 tbl
