Cold-rolled high-quality thin steel plate: mainly includes various high-quality steel cold-rolled thin plates, the most commonly used is carbon structural steel plate, especially cold-rolled thin steel plate for deep drawing, which is cold-rolled thin plate made of low-carbon high-quality steel 08Al. The quality is divided into three groups;1 ,2 and 3, which represent particularly high-grade, high-grade, and higher-finish surfaces, respectively.
Cold-rolled steel plate with smooth surface and excellent processing, used for home appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With the development of the economy, cold-rolled steel sheets have been called necessary materials in modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coil, ordinary cold-rolled, galvanized (electro-galvanized, anti-fingerprint, hot-dip galvanized), galvanized, electro-tinned, color-coated, electrical steel (silicon steel sheet) wait.
Cold rolled steel coils generally use hot-rolled strip steel with a thickness of 1.5-6 mm as the cold rolled billet. The main processes include pickling, cold rolling, degreasing, annealing, leveling, and shearing (cross cutting, longitudinal cutting). If producing coated plates, there are also plating or coating processes such as electroplating tin, hot tin coating, and hot zinc coating. The production process of cold rolled billets is as follows: hot rolled sheet coils (raw materials) - acid washing - cold rolling - degreasing - annealing - leveling - shearing - finished product delivery.
The company's slitting machine, slitting line, cuts cold rolled steel coils into strips of various widths as needed, and then folds the strips into small coils for use in the next process. It is a necessary equipment for precision cutting of transformers, motor industries, and other metal strips. It is mainly used for strip cutting of materials such as tinplate, galvanized iron, silicon steel sheet, cold rolled strip, stainless steel strip, aluminum strip, steel strip, and other coils.
