Embodiment 1
[0029] The zirconium alloy in this embodiment is Zr-2 alloy.
[0030] This embodiment includes the following steps:
[0031] Step 1, mixing metal tin particles, metal iron particles, metal chromium particles, metal nickel particles and sponge zirconium and then pressing to obtain an electrode block;
[0032] Step 2. Assemble the electrode block obtained in step 1 and put it into a vacuum plasma welding box, then vacuumize the vacuum plasma welding box and then fill it with argon, and then use the plasma welding method to weld the electrode block. get self-consumable electrodes;
[0033] Step 3: Put the consumable electrode obtained in step 2 into a vacuum consumable electric arc furnace, then evacuate the vacuum consumable electric arc furnace, and then carry out vacuum consumable smelting by controlling the current to obtain a Ingot casting; the process of vacuum consumable smelting is as follows: in the vacuum consumable electric arc furnace, the vacuum degree is 0.6Pa, an...
