The application discloses an optimized annealing process of N07718 high-temperature alloy foil strip, which comprises the following steps: S1, unwinding, the strip is loaded into an unwinder, the strip is made flat by a straightening roller to enter an annealing furnace; S2, protective gas is filled into the annealing furnace; S3, a gradient temperature rise is carried out on a preheating zone of the annealing furnace, and the temperature of the preheating zone is 300 DEG C-500 DEG C; S4, a heating zone of the annealing furnace is kept warm, the temperature of the heating zone is 1040 DEG C-1060 DEG C, and the strip passes through the heating zone at a speed of 5 m / min-7 m / min; and S5, a fan is used to rapidly cool the strip after annealing. Compared with the prior art, the application can solve the problem of low intermediate heat treatment efficiency of the existing N07718 high-temperature alloy, and the problem of affecting production efficiency is solved.

The invention relates to a cold-press forming and heat treatment method for a spherical composite metal plate. The method comprises the steps of cold-press forming of the spherical composite metal plate, detection after cold-press forming, charging and heat preservation of a heat treatment part, discharging and air cooling of the part, and inspection after heat treatment. The plate is subjected to annular cold pressing from the edge to the center according to preset parameters in stages, gradual uniform plastic deformation of the plate is achieved, and local stress concentration and elastic resilience are remarkably reduced. And in combination with detection after cold pressing forming, the problems that precision control is difficult and the rebound amount is large in the spherical composite metal plate machining process are fundamentally solved. And meanwhile, the heat treatment process is optimized, the residual stress of the spherical composite metal plate is fully released, and then the forming precision and the surface quality of the spherical composite metal plate subjected to heat treatment are improved.
