Embodiment 1
[0021] The method for electroslag remelting of the nickel-based alloy of the present embodiment is the following sequential steps:
[0022] Select the nickel-based alloy to make a steel billet with a thickness of 220mm, and the weight percentage of the nickel-based alloy composition is:
[0023] C: 0.009%, Si: 0.23%, Mn: 0.43%, P: 0.015%, S: 0.001%,
[0024] Al: 0.18%, Cr: 23.23%, Ni: 39.16%, Mo: 2.87%, Cu: 2.05%,
[0025] Ti: 0.83%, the rest is Fe and unavoidable impurities.
[0026] Cut the steel billet into two nickel-based alloy billets with a length of 2210mm, a width of 220mm, and a height of 220mm. , the inner chamfer 4 is the opposite chamfer of two nickel-based alloy billets 1, the length of both sides is 15mm), and the surface of the electrode is polished, with a roughness Ra of 4.35 μm.
[0027] Process the titanium plate into a titanium plate 2 with a width of 100 mm, a length of 300 mm and a thickness of 1.0 mm, add it between two nickel-based alloy bill...
Embodiment 2
[0031] The method for electroslag remelting of the nickel-based alloy of the present embodiment is the following sequential steps:
