Stainless steel tape is a kind of metal material widely used in various industrial fields, known for its excellent corrosion resistance, high temperature properties and mechanical strength. So how is this key material made? The following will briefly introduce the manufacturing process of stainless steel belt.
Preparation of raw materials
The manufacturing of stainless steel belts begins with the selection of appropriate raw materials. Usually, the main components of stainless steel are iron, chromium and nickel, of which chromium content is at least 10.5%, which makes stainless steel has excellent corrosion resistance. In addition to these main components, other elements may be added to improve their properties, such as carbon, manganese, silicon, molybdenum, copper, etc.
Enter the melting stage
In the melting stage, the mixed raw material is put into an electric arc furnace or induction furnace for melting. The temperature inside the furnace usually reaches about 1600 degrees Celsius. The molten liquid steel is refined to remove impurities and gases from it.
Pour into continuous casting machine
The liquid stainless steel is poured into the continuous casting machine, and the stainless steel strip is formed through the continuous casting process. In this process, liquid stainless steel is continuously cast into a rotating mold to form a strip blank of a certain thickness. The cooling rate and temperature control of the mold have an important effect on the quality and performance of the strip.
Enter the hot rolling stage
The billet is hot rolled by a hot rolling mill to form a steel plate with a certain thickness and width. During the hot rolling process, the steel plate is subjected to multiple rolling and temperature adjustments to obtain the desired size and properties.
Pickling stage
In this process, the stainless steel strip is soaked in an acidic solution to remove surface oxides and impurities. The surface of the stainless steel strip after pickling is smoother, which provides a good foundation for subsequent cold rolling and surface treatment.
The cold rolling stage
At this stage, the stainless steel strip is further rolled through a cold mill to further adjust its thickness and flatness. The cold rolling process can improve the surface quality and precision of the stainless steel strip.
Final stage
After a series of post-treatment processes such as annealing, polishing and cutting, the stainless steel strip finally completes the manufacturing process. The annealing process can eliminate the stress inside the stainless steel strip, improve its plasticity and toughness; Polishing process can make the surface of the stainless steel strip more smooth and bright; The cutting process cuts the stainless steel strip to the desired length and width as needed.
In summary
The manufacturing process of stainless steel strip involves raw material preparation, melting, continuous casting, hot rolling, pickling, cold rolling and post-treatment and other links. Each step requires precise control of process parameters and quality standards to ensure that the final product meets quality requirements. The wide application of stainless steel strips is due to its excellent corrosion resistance and mechanical properties, and the fine control of the manufacturing process is the key to achieving these properties.
