What is the production process of stainless steel plates?

Stainless steel plate is a metal plate with corrosion resistance and high temperature resistance. It is widely used in construction, chemical industry, electric power, aviation and other fields. The following is the production process of stainless steel plates.

1. Raw material preparation: The main raw materials of stainless steel plates are steel, chromium, nickel and other metals. First, select appropriate raw materials and mix them according to different requirements and specifications.

2. Smelting: Put the raw materials into a large furnace and heat them to high temperatures to melt them. Through smelting, the composition of stainless steel can be adjusted and controlled to ensure product quality and performance.

3. Continuous casting: Pour the molten stainless steel into the continuous casting machine, and quickly solidify it into a billet through the crystallizer and cooling water. Continuous casting machines can produce steel billets of different specifications and sizes.

4. Hot rolling: The steel billet is fed into the hot rolling mill and rolled and stretched multiple times to gradually thin it and form the required thickness and width. During the hot rolling process, stainless steel plates undergo deformation under high temperatures and pressures to achieve the required mechanical properties.

5. Pickling: The hot-rolled stainless steel plate has some scale and impurities and needs to be cleaned by pickling. The stainless steel plate is immersed in the acid solution to remove oxides and impurities on the surface while increasing the brightness of the stainless steel plate.

6. Cold rolling: The pickled stainless steel plate enters the cold rolling mill. Through multiple rolling and stretching, the thickness of the stainless steel plate is further reduced and its surface quality and flatness are improved.

7. Annealing: The cold-rolled stainless steel plate will generate a certain amount of stress and needs to be annealed. The stainless steel plate is heated to a high temperature and then slowly cooled. During the annealing process, the grain boundaries of the stainless steel plate are recrystallized, eliminating stress and improving tensile strength and plasticity.

8. Surface treatment: According to different needs, the stainless steel plate is subjected to surface treatment, such as polishing, pickling, coating, etc., to increase the aesthetics and corrosion resistance of the stainless steel plate.

9. Cutting and flattening: Cut and flatten the stainless steel plate according to the size required by the customer to obtain the final product.

10. Inspection and packaging: Carry out quality inspection on stainless steel plates to ensure that they meet relevant standards and requirements. The finished product is then packaged for shipping and storage.

The above is the production process of stainless steel plates. These steps can ensure the quality and performance of stainless steel plates and meet the needs of various applications.

Stainless steel plate is a metal plate with corrosion resistance and high temperature resistance. It is widely used in construction, chemical industry, electric power, aviation and other fields. The following is the production process of stainless steel plates.

Characteristics of copper pipes

Lightweight, with good thermal conductivity and high low-temperature strength. Commonly used in the manufacturing of heat exchange equipment (such as condensers). It is also used for assembling low-temperature pipelines in oxygen production equipment. Copper pipes with small diameters are commonly used for conveying pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and as pressure measuring pipes for instruments.

Advantages of I-beams

I-shaped beams are hollow web members. For high-strength materials, hollow web members are better than solid web members in terms of weight, material, and labor saving. This cross-sectional design mainly uses the flange farthest from the centroid to resist bending moments (because the farther the flange is, the greater the moment of inertia), and mainly uses the web to resist shear. As for the inconvenience in making it, it can be solved by factory or molding. Saving materials, labor, and time is efficiency.

How are stainless steel pipes classified?

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, as well as bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements. There are various types and uses of stainless steel pipes, with varying technical requirements and production methods. The current production of steel pipes has an outer diameter range of 0.1-450mm and a wall thickness range of 0.01-250mm. To distinguish its characteristics, steel pipes are usually classified according to the following method.

How to store corrugated boards?

Stacking method: Corrugated boards should be stored flat and should not be stacked too high to avoid deformation or damage caused by excessive pressure. When stacking, care should be taken to avoid direct contact with sharp objects or heavy objects.

Preparation method of carbon steel pipe

The raw material of carbon steel pipe is round tube blank, which needs to be cut and processed by a cutting machine to form a billet with a length of about 1 meter, and then sent to the furnace for heating through a conveyor belt. The billet is fed into the furnace for heating, with a temperature of approximately 1200 degrees Celsius.
