Production process of stainless steel sheet: analysis of the manufacturing process of high-quality products
The production process of stainless steel sheet is crucial for manufacturing high-quality products. High quality stainless steel plates should have excellent mechanical properties, surface quality, and corrosion resistance. Below is an analysis of the general production process for stainless steel plates:
1. Raw material preparation: The main raw material for stainless steel sheet is stainless steel coil, usually produced by cold rolling or hot rolling processes. The selection and quality of raw materials have a significant impact on subsequent production processes and final product quality.
2. Acid washing: Stainless steel coils may be contaminated with rust stains, oxide scales, and other impurities during the production process, which need to be removed through acid washing technology. Acid washing can ensure the cleanliness and smoothness of the surface of the board, preparing for subsequent processes.
3. Cold rolling or hot rolling: After pickling, stainless steel coils can be subjected to cold rolling or hot rolling. Cold rolling is the process of rolling a coil material through a roller conveyor to achieve the desired thickness while improving surface smoothness. Hot rolling is the process of rolling a coil into the desired thickness under high temperature conditions, suitable for the production of thick plates.
4. Acid washing and reprocessing: Cold rolled or hot-rolled stainless steel plates are subjected to acid washing again to remove residual impurities on the surface and ensure surface quality.
5. Annealing: Annealing is an important process in the production of stainless steel plates. By heating the plate to a certain temperature and then slowly cooling it, the stress of the plate can be eliminated, the mechanical properties and plasticity can be improved, and the corrosion resistance of the plate can be improved.
6. Surface treatment: Stainless steel sheets can undergo various surface tre
