The Advantages and Application of Cold Rolled Steel Plate
Cold rolling is made of hot-rolled coils as raw materials, which are rolled at room temperature below the recrystallization temperature. Cold rolled steel plates are steel plates produced through the cold rolling process, referred to as cold plates. The thickness of cold-rolled sheet is generally between 0.1 and 8.0mm. The thickness of cold-rolled sheet produced by most factories is less than 4.5mm. The thickness and width of cold-rolled sheet are determined according to the equipment capacity and market demand of each plant.
Advantages of Cold Rolled Steel Plate
1. Cold rolled steel plate is one of the most common products in the steel production industry, but its main production principle is actually very simple, and the raw material is hot-rolled plate, which is below the recrystallization temperature at room temperature Steel products formed by rolling work, although these products are likely to have hot temperatures after being manufactured, but they are made at room temperature during the production process, so they are still called cold-rolled sheets.
2. Compared with the traditional hot-rolled sheet, the advantages of cold-rolled steel sheet are still very obvious, not only can it have more accurate size and uniform thickness, but also the error in thickness difference is extremely small, so It is more in line with the demand for high-precision steel products. In addition, the strip produced by the cold rolling method will have a thickness that cannot be produced by the hot rolling method, which can make the strip lighter and thinner.
3. The shape of the cold-rolled steel sheet is also more excellent, it will not have the shortcomings of hot rolled sheet strips or oxide scale, not only looks beautiful, but also can be produced according to the different needs of users Products with different roughness on the surface, these are the works that the hot rolled plate cannot achieve.
4. The mechanical and technological functions of cold-rolled steel sheets are also extremely excellent, not only high strength, but also other extremely good performance premises. The production efficiency at the time of production is also extremely high, which can achieve extremely fast rolling The process is generally divided into two types: single-piece rolling or coil rolling. Either way, it can achieve a good continuous rolling speed. Various advantages make cold-rolled plates become industrial. The most popular choice in the strip production process.
Application of Cold Rolled Steel Plate:
Cold rolled steel plate are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food canning, etc. The cold plate is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold rolled to make a steel plate with a thickness of less than 4mm. Since rolling at room temperature does not produce scale, therefore, the surface quality of the cold plate is good, the dimensional accuracy is high, and the annealing treatment, its mechanical properties and process performance are better than hot-rolled thin steel plate, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled thin steel plates.
