0.015mm! The world's thinnest, successfully rolled

2023-12-06

China has successfully rolled 0.015mm ultra-thin hand-shredded steel using domestically produced equipment. This is currently the thinnest stainless steel in the world and a major breakthrough in process technology.

Hand-tearable steel, that is, stainless steel that can be torn by hand, scientifically known as stainless steel foil, is a thin steel material that is widely used in many fields such as aerospace, electronics, new energy, and medical equipment. It can be seen on airplanes, photovoltaic power generation panels, and even on folding mobile phone screens. Due to its excellent material performance, technical difficulty, and high equipment precision, hand-shredded steel has the reputation of "the crown jewel of the steel industry."

In the future, we will further improve the technical level, reduce the rolling thickness, and continue to innovate and create strength in the field of hand-shredded steel.

1. The center positions of the two ends are different

The center points of the two ends of the stainless steel eccentric reducer are not on the same axis.

The center points of the two ends of the stainless steel concentric reducer are on the same axis.

2. Different operating environments

One side of the stainless steel eccentric reducer is flat. This design facilitates exhaust or liquid drainage and facilitates maintenance. Therefore, it is generally used for horizontal liquid pipelines.

The center of the stainless steel concentric reducer is on a line, which is conducive to fluid flow and has less interference with the flow pattern of the fluid during diameter reduction. Therefore, it is generally used for diameter reduction of gas or vertical liquid pipelines.

3. Different installation methods

Stainless steel eccentric reducers are characterized by simple structure, easy manufacturing and use, and can meet a variety of pipeline connection needs. Its application scenarios mainly include:

Horizontal pipe connection: Since the center points of the two ends of the stainless steel eccentric reducer are not on the same horizontal line, it is suitable for the connection of horizontal pipes, especially when the pipe diameter needs to be changed.

Pump inlet and regulating valve installation: The top flat installation and bottom flat installation of the stainless steel eccentric reducer are suitable for the installation of the pump inlet and regulating valve respectively, which is beneficial to exhaust and discharge.

Stainless steel concentric reducers are characterized by less interference to fluid flow and are suitable for reducing the diameter of gas or vertical liquid pipelines. Its application scenarios mainly include:

Gas or vertical liquid pipeline connection: Since the center of the two ends of the stainless steel concentric reducer is on the same axis, it is suitable for the connection of gas or vertical liquid pipelines, especially where diameter reduction is required.

Ensure the stability of fluid flow: The stainless steel concentric reducer has little interference with the fluid flow pattern during the diameter reduction process and can ensure the stability of the fluid flow.

4. Selection of eccentric reducers and concentric reducers in practical applications

In actual applications, appropriate reducers should be selected according to the specific conditions and needs of pipeline connections. If you need to connect horizontal pipes and change the pipe diameter, choose stainless steel eccentric reducers; if you need to connect gas or vertical liquid pipes and change the diameter, choose stainless steel concentric reducers.
