FIELD: non-ferrous metallurgy, possibly in shops for producing aluminum by electrolysis in order to determine efficiency of electrolysis baths.
SUBSTANCE: method comprises steps of placing in electrolysis bath ceramic or carbon tubes in such a way that to receive in first tube cleaned metal surface and to receive in second tube electrolyte surface; measuring levels of said surfaces by means of ultrasound pickups and according to results of said measurements finding real values of levels of metal and electrolyte; according to averaged values calculating metal volume increase and current value of electrolysis bath efficiency. Such method may be effectively used for monitoring melt metal volume increase and efficiency of powerful electrolysis baths with electric current intensity exceeding 200 kA and also for optimization of manufacturing process in any type of electrolysis baths.
EFFECT: enhanced accuracy of determining efficiency of electrolysis baths.
