FIELD: chemistry.
SUBSTANCE: method includes detecting information indicative of a thermite reaction, comparing information indicative of a thermite response with a threshold value, generating a thermal response signal according to comparison, and responding to a thermite response by adjusting the cell operating mode. As an indicator, one of the indicators is used, including voltage, voltage drop, current, electric field and a magnetic field associated with one or more anodes. An aluminium electrolysis cell having a device for said monitoring is disclosed.
EFFECT: possibility of eliminating damage to the cell by preventing the occurrence of a thermite reaction.
