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.
