[0033] Specifically, among them, the annealing temperature set includes multiple annealing temperature values, and among them, the pickling time set includes multiple pickling times.

[0034] It should be explained that equal interval division means dividing the interval into several sub-intervals at a fixed step length within the given interval. The annealing temperature set refers to a set of a series of specific temperature values generated from the annealing temperature range by the equal interval division method. The pickling time set refers to a set of a series of specific time values generated from the pickling time range by the equal interval division method.

Sequentially extract an annealing and pickling matching group from the annealing and pickling matching group set, and perform the following operations on each extracted annealing and pickling matching group: Use the annealing temperature value in the annealing and pickling matching group to perform an annealing operation on the nickel coil strip to obtain an annealed nickel coil strip.

[0042] Specifically, the step of using the annealing temperature value in the annealing and pickling matching group to perform an annealing operation on the nickel coil strip to obtain an annealed nickel coil strip includes: Obtain an annealing furnace, and import the nickel coil strip into the annealing furnace to obtain a nickel coil strip to be heated; Obtain the best mixed gas combination, and set the temperature according to the annealing temperature value in the annealing and pickling matching group and a pre-constructed thermocouple to obtain a heating temperature, where the thermocouple is located in the annealing furnace; Obtain a heating environment according to the heating temperature, the best mixed gas combination, and the annealing furnace; Use the heating environment and a preset heating time to heat the nickel coil strip to be heated to obtain a heated nickel coil strip; Use a preset cooling time to perform a cooling operation on the heated nickel coil strip to obtain an annealed nickel coil strip.

[0043] It should be explained that an annealing furnace refers to a device specifically used for annealing metal materials. By controlling the temperature and gas, the metal material undergoes a tissue change to improve the performance of the metal material. The annealing furnace in the embodiment of the present invention refers to a device for annealing nickel coil strips.

[0046] Exemplarily, there are multiple historical gas detection time periods: The historical gas detection time period A is 8:00 on December 2, 2024, the historical gas detection time period B is 9:00 on December 2, 2024, and the historical gas detection time period C is 10:00 on December 2, 2024. Extract one historical gas detection time period A from the multiple historical gas detection time periods. The current gas volume is obtained as 0, and the preset mixed gas volume is 50. Perform a gas filling operation on the current gas volume using the preset mixed gas volume to obtain an accumulated gas volume of 50. Burn the spare nickel coil strip using the accumulated gas volume to obtain a burned nickel coil strip and a combustion gas concentration. Evaluate the burned nickel coil strip and the combustion gas concentration. If the final comprehensive evaluation score is less than the preset comprehensive evaluation threshold, then eliminate the historical gas detection time period A. Summarize the remaining historical gas detection time periods B and C to obtain multiple updated historical gas detection time periods. Use the multiple updated historical gas detection time periods as the multiple historical gas detection time periods, and use the accumulated gas volume of 50 as the current gas volume of 50. Extract the next historical gas detection time period B from the multiple historical gas detection time periods. The comprehensive evaluation score of the historical gas detection time period B is greater than or equal to the preset comprehensive evaluation threshold.
