Embodiment 1
[0015] A kind of cold-rolling process of nickel-base superalloy precision steel strip, it comprises the following steps:
[0016] (1) Nickel-based superalloy strips with a thickness of 1.0 mm are used as raw materials, and rolled at room temperature on a 20-high rolling mill. The rolls are lubricated and cooled with lubricating oil to reduce the friction coefficient on the contact surface during the rolling process. Reduce the rolling pressure and the required transmission power, as well as the damage of the roll to the surface of the steel strip. According to the properties of the nickel-based superalloy material, the first rolling process rolled 6 passes in total, the rolling speed was set at 80 mpm, the actual rolling force was 1158 kN, the reduction was 60%, and the obtained strip thickness was 0.4 mm;
[0017] (2) Annealing the semi-finished nickel-based superalloy strip in step (1);
[0018] (3) The semi-finished high-temperature alloy strip in step (2) is rolled for th...

[0023] A kind of cold-rolling process of nickel-base superalloy precision steel strip, it comprises the following steps:
[0024] (1) Nickel-based superalloy strips with a thickness of 1.2 mm are used as raw materials, and rolled at room temperature on a 20-high rolling mill. The rolls are lubricated and cooled with lubricating oil to reduce the friction coefficient on the contact surface during the rolling process. Reduce the rolling pressure and the required transmission power, as well as the damage of the roll to the surface of the steel strip. According to the properties of the nickel-based superalloy material, the first rolling process rolled 6 passes in total, the rolling speed was set at 80mpm, the actual rolling force was 1882kN, the reduction was 68%, and the obtained strip thickness was 0.4mm;
[0025] (2) Annealing the semi-finished nickel-based superalloy strip in step (1);
[0026] (3) The semi-finished high-temperature alloy strip in step (2) is rolled for the s...
