Problems solved by technology

Precision steel strips usually refer to steel strips with a thickness of less than 0.3mm, which are high-end products in steel strips. However, the current domestic high-temperature alloy precision strip manufacturing process is complicated and the production cycle is long. The conventional rolling process cannot meet the needs of the high-end market.

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;

Abstract

The invention provides a cold rolling process for a nickel-based high-temperature alloy precision steel belt. The cold rolling process comprises the following parameters such as the rolling pass, therolling speed, the actual rolling force, the material rolling reduction, the degreasing fluid compounding rate, the degreasing speed and the degreasing liquid temperature; and finally, a high-temperature alloy precision belt material with the thickness ranging from 0.05 mm to 0.1 mm is finally obtained. Compared with the prior art, the nickel-based high-temperature alloy precision belt material has the advantages of being resistant to high temperature and corrosion, high in strength and the like; and the rolling process is simple and easy to implement.

Description

technical field [0001] The invention relates to a cold-rolling process of a nickel-based high-temperature alloy precision steel strip, which belongs to the field of metal material production and processing. Background technique [0002] With the vigorous development of the aerospace industry, the operating temperature of practical hot-end components such as combustion chambers and afterburners is getting higher and higher, and materials with better temperature bearing capacity are required. Nickel-based superalloy materials are widely used in the manufacture of aero-engine parts because of their good high temperature resistance, corrosion resistance, high strength, and high reliability. Precision steel strips usually refer to steel strips with a thickness of less than 0.3mm, which are high-end products in steel strips. However, the current domestic high-temperature alloy precision strip manufacturing process is complicated and the production cycle is long. The conventional r...
