FIELD: electrolytic reduction of aluminum.
SUBSTANCE: proposed electrolyzer includes many collecting rods. Each collecting rod has elongated first section which is brought in contact with cathode and at least one end section which passes through one of side walls of electrolyzer and is electrically connected with electric current carrier. Specific feature of electrolyzer consists in availability of core in each first section of each collecting rod for control of current distribution; this core is made from material possessing high specific electric conductivity and external envelope made from material of higher mechanical strength and chemical resistance as compared with material of core; end section of each collecting rod is made from material of low specific heat conductivity.
EFFECT: reduced losses of heat; maintenance of specific thermal balance of cathode; reduced power requirements.
