Introduction of Slitting Machine for Cold Rolled Steel Plate

The Rishbin slitting machine is widely applicable to the processing of cold-rolled steel plate and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and various kinds of metal coils after surface coating. Previously, we explained in detail the small knowledge of electrolytic plates and galvanized steel plates. Of course, the Rishbin steel slitter is also used for processing electrolytic plates and galvanized steel plates. The following takes Rishbin Machinery as an example to explain the relevant knowledge about cold rolled steel sheet.
Cold rolling is actually based on hot-rolled coils as raw materials, and various profiles are rolled at room temperature. Cold-rolled steel plates are cold-rolled steel plates, commonly known as cold plates. The thickness of cold-rolled steel sheets is generally 0.1-8.0 mm. Most cold-rolled steel sheets produced by factories are less than 4.5 mm in thickness. The thickness and width of cold-rolled steel sheets are determined according to the plant's equipment capacity and market demand. The use of cold-rolled plates in industrial production is quite extensive, such as automotive manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans and so on. Therefore, the production of cold-rolled steel sheets in the market is also quite numerous, and the productivity is high. Besides, there are many varieties. While,its production process is continuous and easy to mechanize automation. Common methods for producing cold-rolled sheets include rolling, forging, extruding, drawing and son on.

Cold rolling is a steel plate that is further rolled to a target thickness at room temperature. It is an abbreviation for ordinary cold rolled carbon structural steel. It is also called a cold rolled plate and is commonly called a cold plate. It is sometimes mistakenly written as another name as well. Compared with cold-rolled and hot-rolled steel plates, the thickness of cold-rolled steel plates is more accurate, and the surface is smooth and beautiful, but the mechanical properties are poor, especially in terms of processability. Cold-rolled rolls are less suitable for processing because they are more brittle. Under normal circumstances, cold-rolled steel sheets are required to be given to customers after annealing and surface smoothing. However, the surface quality of the cold plate is good, and the dimensional accuracy is high. Besides, the annealing process is performed. The mechanical properties and process performance of the cold plate are superior to those of the hot-rolled steel plate. Therefore, in many fields, especially in the field of home appliance manufacturing, hot rolled steel sheets have gradually been replaced by them.
