Embodiment 1
[0034] Example 1. A triple smelting process of a difficult-to-deform nickel-based superalloy GH4151
[0035] This example mainly describes a triple smelting process of a hard-to-deform nickel-based superalloy GH4151. The triple smelting process is specifically vacuum induction furnace smelting (VIM) + protective atmosphere electroslag remelting (P-ESR) + vacuum Consumable remelting (VAR) smelting. The diameter of alloy ingots for vacuum induction furnace smelting (VIM) is 360mm, the diameter of alloy ingots for protective atmosphere electroslag remelting (P-ESR) is 450mm, and the diameter of alloy ingots for vacuum consumable remelting (VAR) is 508mm.
[0036] The process flow of vacuum induction melting (VIM) includes the following steps:
[0037] Step 1.1: According to the composition requirements of the GH4151 alloy, weigh the raw materials. The weight percentage (wt.%) of each raw material is: C0.04, Co 14.0, Cr 10.0, Mo 4.0, W 2.5, V 0.40, Ti 2.50, Al 3.5, Nb 3.0, S=0.0...
