Abstract

The invention discloses a high-temperature oxygen-controlled magnetic drive liquid metal rotating corrosion experimental device and a method. The device comprises a tiltable supporting frame, an innertank body, an outer tank body, a tank lid, a sealing assembly, a motor and a reducer, an outer magnetic rotor, an isolation sleeve, an inner magnetic rotor, a clamping coupler, a transmission shaft,a disc-shaped sample holder, a smelting tank, a material inlet, a gas inlet and outlet, a pressure gauge, a pressure reducing valve, a main heater, a spare heater, an insulation layer, a temperature sensor, a main control cabinet and other parts. The motor and the reducer drive the inner magnetic rotor through a magnetic coupler to achieve the non-contact torque transmission of a static seal structure and drive the sample holder to rotate in the liquid metal. According to the principle of relative motion, the continuous flow corrosion experimentsof low activated steel and a welding seamthereofare carried out in the liquid metalto observe the surface topography of the sample and analyze the corrosion mechanism and to provide basic data for the compatibility study between the liquid metal and fusion reactor structural materials. According to the high-temperature oxygen-controlled magnetic drive liquid metal rotating corrosion experimental device and the method, the reliability and workefficiency of the device are greatly improved.
