An exhaust pipe is arranged at the top of the heating furnace 26, and an eighth valve 22 is arranged on the exhaust pipe; the molecular weight of the inert gas is greater than the average molecular weight of air, and argon is preferred.
And the sodium supply mechanism is connected with the interior of the heating furnace 26 and is used for introducing liquid sodium into the heating furnace 26. The sodium supply mechanism comprises a sodium storage tank 1, the sodium storage tank 1 is positioned above the heating furnace 26 and is connected with the upper part of the heating furnace 26 through a sodium pipeline; the heating device 2 is sleeved outside the sodium storage tank 1 and used for heating the inside of the sodium storage tank 1; and a fifth valve 3 and a first valve 5 are sequentially arranged between the sodium storage tank 1 and the heating furnace 26 on the sodium pipeline, and a quantitative pump 4 is arranged between the fifth valve 3 and the first valve 5 on the sodium pipeline.
Since sodium is solid, sodium liquefies under the heating of the heating device 2, and flows into the creep tester 25 in a constant amount and speed by the action of the quantitative pump 4. The sodium storage tank 1 is stored with sodium, the heating device 2 can be a high-temperature environment box, the sodium storage tank 1 is arranged in the high-temperature environment box, and the sodium storage tank 1 is heated by the high-temperature environment box to melt the sodium in the sodium storage tank 1 into liquid.
A sodium recovery mechanism comprising a sodium recovery tank 14; a sodium discharge port is formed in the bottom of the heating furnace 26, and the sodium recovery tank 14 is positioned below the sodium discharge port and is communicated with the sodium discharge port; and a liquid discharge valve 13 is also arranged at the sodium discharge port. The sodium in the creep fatigue machine 25 (heating furnace 26) can flow into the sodium recovery tank 14 by gravity, and the sodium can be recycled.

The inert gas is preferably argon gas because its molecular weight is larger than the average molecular weight of air, the eighth valve 22 should be opened when liquid sodium is added into the heating furnace 26, at this time, the liquid sodium discharges argon gas through the eighth valve 22, air cannot enter the heating furnace 26 through the eighth valve 22 because its molecular weight is smaller than that of argon gas, if a small amount of liquid sodium appears at the eighth valve 22, it is proved that the liquid sodium is full, and then the first valve 5 and the eighth valve 22 are closed. If the creep fatigue tester is not used for a long time, the liquid sodium in the eighth valve 22 should be removed.
(2) And then liquid sodium material is introduced into the heating furnace 26 by the sodium supply mechanism, so that the workpiece arranged in the heating furnace 26 is corroded by the liquid sodium in a high-temperature environment, and the structural performance of the workpiece is judged according to the corrosion degree of the workpiece.
