Example Embodiment
[0023] Example 1
[0024] The production process of high temperature resistant and elastic nickel-chromium alloy strip is: batching → vacuum induction melting → vacuum consumable smelting → homogenization → billeting → hot forging → hot rolling → solution treatment → pickling → cold rolling → finished annealing → package.
[0025] In the batching process, the weight ratio of each component of the high temperature and elastic nickel-chromium alloy strip is: C: 0.03%, B: 0.005%, Al: 1.5%, Ti: 2.0%, Cr: 19.5%, Mo: 8.5% , Co: 10.0%, the rest is Ni.
[0026] In the homogenization process, a two-stage soaking method is adopted. After the temperature is kept at 850°C for 3 hours, the temperature rise rate is 55°C / h to 1180°C and the temperature is kept for 30 hours.
[0027] In the hot forging process, the opening forging temperature is 1150°C and the final forging temperature is 1030°C.
[0028] In the hot rolling process, the heating temperature is 1160°C, the finishing temperature is 1000...

[0037] In the batching process, the weight ratio of each component of the high temperature and elastic nickel-chromium alloy strip is: C: 0.03%, B: 0.006%, Al: 1.6%, Ti: 2.1%, Cr: 20.5%, Mo: 8.8% , Co: 10.5%, the rest is Ni.
[0038] In the homogenization process, a two-stage soaking method is adopted. After holding at 860°C for 3, the temperature is increased to 1200°C at a heating rate of 50°C / h, and the holding time is 30h.
[0039] In the hot forging process, the opening forging temperature is 1150°C and the final forging temperature is 1030°C.
[0040] In the hot rolling process, the heating temperature is 1165°C, the finishing temperature is 1010°C, the thick...
