All You Need To Know About Stainless Steel Cold Rolled Strip

What is the Stainless Steel Cold Rolled Strip?

Modern end-users have increasingly strict requirements for Stainless Steel Cold Rolled Strips. Unlike traditional hot-rolled stainless steel strips, precision cold-rolled stainless steel strip usually refers to a strip with a thickness of less than 0.30mm.

As a high-end product in the field of stainless steel materials, precision cold-rolled stainless steel has excellent strength, precision, surface finish, and other properties. They are widely used in stainless steel strip applications, cables, subcutaneous injection needles, diamond-cutting tools, and spring materials.

At present, the main production processes for cold-rolled stainless steel strips include cold rolling, bright annealing, tension leveling, and finishing.

The Rolling Process for Stainless Steel Cold Rolled Strip Materials

The ultra-thin performance requirements, high strength, and high precision of cold-rolled stainless steel strips place high demands on the rolling process.

Conventional rolling processes are unable to meet the production requirements for precision cold-rolled stainless steel strips. Currently, Z-Mills or 20-roll Sendzimir Mills are mainly used for the production of precision stainless steel strips.

The complete production process includes cold rolling, annealing, and finishing. During the rolling process, it is important to select an appropriate reduction system, tension system, speed system, and roll shape.

To increase the production capacity of the rolling mill, the reduction rate should be maximized to reduce the number of rolling passes while fully utilizing the main drive power of the rolling mill and the front and rear coilers. Tension can reduce rolling pressure, improve rolling shape, and stabilize the rolling process. High tension is generally used in 20-roll rolling mills.

At the same time, adjustments should be made based on the plate shape. When there are waves in the material, the tension should be reduced to pull the edge of the belt or break the belt. When there is a side wave in the strip, the tension can be appropriately increased.

Within the allowable speed range of the rolling mill, the rolling speed should be as high as possible to increase the production capacity of the rolling mill. At the same time, when the rolling speed increases, the rolling pressure decreases accordingly. In the first pass, a lower rolling speed is usually used. According to cold rolling principles, it is necessary to use as small a diameter as possible for the working rolls under maximum pressure conditions.

With minimizing the diameter of the working rolls as the goal, multi-roll rolling mills including 6, 12, and 20 have been developed. Among them, 20-roll rolling mills are preferred for precision cold-rolled stainless steel strip production due to their high rigidity, small elastic deflection, and deformation of rolls.

Advantages of Using Stainless Steel Cold Rolled Strip

Stainless steel cold rolled strip is made by further cold rolling of hot rolled stainless steel strip coil. Compared with hot-rolled stainless steel strips, it has higher dimensional accuracy, low surface roughness, good surface quality, smoothness, and higher strength. Therefore, thinner cold-rolled stainless steel strips can replace thicker hot-rolled steel strips for the same purpose, which can save steel consumption and have significant economic significance.
