METHOD FOR THERMAL CONTROL OF MAGNESIUM ELECTROLYTIC PRODUCTION PROCESS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC C25C3/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to non-ferrous metallurgy, namely to a method for thermal control of the process of electrolytic magnesium production and a device for its implementation. Method involves removal of heat from the electrolyte by removal of gases from the cell of the electrolysis cell, maintenance of optimum temperature of the electrolyte and control of temperature at deviations from optimum. Control of temperature of electrolyte at deviation from optimum by change of volume of removal of gases and convective heat losses from assembly cell of electrolyzer. Proposed device comprises collector of sanitary-technical suction with damper connected with electrolyzer made up of lined tank divided by partition into electrolytic compartment and collecting cell with cover. Gate installed on sewage collector is made in form of vertically rotating plate with handle, position of which is fixed to ensure removal of required volume of sanitary-engineering suction gases, collecting cell is additionally equipped with an upper frame made in the form of a metal frame of rectangular shape from U-shaped profiles, and cover of the assembled cell is installed horizontally and sealed by sand shutter.

EFFECT: technical result is stabilization of temperature mode of process of electrolytic obtaining of magnesium, reduction of losses of magnesium and increase of output of magnesium by current.
