The application discloses an electric heating zero-emission magnesium reduction device and a process thereof, and the reduction device comprises a reduction tank, a condensation tank is sealingly connected to the upper end of the reduction tank through a flange, a crystallizer is arranged in the condensation tank, a vacuumizing device is further connected to the condensation tank through a pipeline, a plurality of inner electric heaters are inserted into the reduction tank from the bottom, and an outer electric heater is further wrapped outside the reduction tank; the gas heating in the traditional Pidgeon process is replaced by electric heating, so that the very serious pollution emission is changed into zero emission; and the various high-temperature corrosion of the traditional reduction tank under the gas flame barbecue is changed into basically zero corrosion, the service life of the reduction tank is greatly prolonged, and a large amount of steel is saved; the temperature control of the traditional Pidgeon process is difficult, leading to poor quality of the reduced magnesium, and the electric heating can realize accurate control of the temperature and improve the quality of the reduced magnesium.
