What is the production process of stainless steel plates?


Author:

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.
