Embodiment 1

[0015] A precision stainless steel strip cold rolling process for steel structure buildings, comprising the following steps:

[0016] 1. The stainless steel strip with a thickness of 1.5mm is used as the raw material, and the first cold rolling is carried out in the 20-high rolling mill. The rolling mill uses cold rolling lubricating oil to reduce the friction coefficient on the contact surface between the roll and the steel strip, and reduce the rolling effect. The rolling pressure and the required transmission power are used to cool the roll and the stainless steel strip. After the first rolling pass is completed, reverse rolling is carried out, and the reversible rolling is repeated. There are 8 cold rolling passes, and the rolling speed of the first pass is 100m / min, the rolling speed from the second pass to the eighth pass is 120m / min, and the stainless steel strip is rolled to a thickness of 0.6mm.

[0017] 2. The above-mentioned semi-finished stainless steel strip is de...

Embodiment 2

[0023] A precision stainless steel strip cold rolling process for steel structure buildings, comprising the following steps:

[0024] 1. The stainless steel strip with a thickness of 2.0mm is used as the raw material, and the first cold rolling is carried out in the 20-high rolling mill. The rolling mill uses cold rolling lubricating oil to reduce the friction coefficient on the contact surface between the roll and the steel strip, and reduce the rolling effect. The rolling pressure and the required transmission power are used to cool the roll and the stainless steel strip. After the first rolling pass is completed, reverse rolling is carried out, and the reversible rolling is repeated. There are 8 cold rolling passes, and the rolling speed of the first pass is 120m / min, the rolling speed of the second pass to the eighth pass is 140m / min, and the stainless steel strip is rolled to a thickness of 0.4mm.

Abstract

The invention discloses a cold rolling process of a precise stainless steel band for a steel structure building. The cold rolling process comprises the following steps: primary rolling for 8 times; cleaning by degreasing; primary annealing; secondary rolling for 6 times; secondary annealing; and stretch bend straightening, leveling, tailoring, packing and storing. The precise stainless steel band which is 0.1-0.25 mm thick is obtained according to the cold rolling process: primarily rolling, degreasing, primary annealing, secondary rolling, secondary annealing and straightening. The precise stainless steel band for the steel structure building has the advantages of being high in strength, light in self weight, stable in extension property, small in thickness tolerance, and low in possibility in generating cracks in punching.

Description

technical field [0001] The invention belongs to the field of stainless steel strip production, in particular to a precision stainless steel strip cold rolling process for steel structure buildings. Background technique [0002] In recent years, compared with brick-concrete structures, steel structures have obvious advantages in terms of environmental protection, energy saving, high efficiency, and factory production. With the rapid development and transformation of communication, electronics, and office automation equipment, users have increasingly stringent requirements for stainless steel strips. Precision stainless steel strips usually refer to stainless steel strips with a thickness of less than 0.3mm. Precision stainless steel strips are high-end in the field of stainless steel strips. Products, with excellent strength, precision, surface finish and other properties, are widely used in electronic stamping parts, optical cables, diamond blades, etc. The performance requ...
