CONTROL METHOD OF DISTRIBUTION IN ALUMINIUM ELECTROLYTIC CELLS Russian patent published in 2009 - IPC C25C3/20 

FIELD: metallurgy.

SUBSTANCE: invention relates to non-ferrous metallurgy, particularly to electrolytic receiving of aluminium from alumina, and can be used on electrolytic cells as with self-calcinating anode, as with roasted for control of distribution in anode complex and bottom for the purpose of stabilisation of process variables. Measurements of current strength of complex is implemented by means of electromagnetic transducers, installed for each current-carrying and/or shunting element of electrolytic cell, it is defined total signal from all electromagnetic transducers, it is discovered constant of proportionality by means of division of current strength of complex, measured at a moment of pick-off from sensors, for total signal from all electromagnetic transducers, and subject to proportionality constant it is find current strength value in each current-carrying and/or shunting electrolytic cell element, received values are coded and transmitted through telecommunications into automatic control system for reception of required technological influence.

EFFECT: increasing of measurement accuracy by current-carrying and/or shunting electrolytic cell elements.
