Products Description
Cold-rolled steel coils use hot-rolled coils as raw materials and are rolled under recrystallization, but are generally understood to be rolling using normal-temperature rolled materials. Three to six continuous rolling mills are used as cold rolling equipment, and those delivered in coils are called cold rolled steel sheet .
Cold-rolled steel coils have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling. High flatness, high surface finish, clean and bright surface of cold-rolled sheet. It is easy to be coated and processed and has the characteristics of high stamping performance and low yield point, so cold-rolled steel coil has a wide range of uses, mainly used in automobiles and building materials. At the same time, it is also the substrate for the production of galvanized steel sheets in coil andAlu-Zinc steel coil.
Products features
1. The product size of cold-rolled coils is accurate, the thickness is uniform, and the thickness difference of the coils generally does not exceed 0.01-0.03mm or less, which can fully meet the requirements of high-precision tolerances.
2. Available to extremely thin strips that cannot be produced by hot rolling (the thinnest can reach 0.001mm or less.
3. The surface quality of cold-rolled products is superior, and there are no defects such as pits and pressed iron oxide scales that often occur in hot-rolled coils. And according to the requirements of users, it can produce coils with different surface roughness (glossy surface or hemp rough surface, etc.) to facilitate the processing of the next process.
4. The mechanical properties and technological properties of cold-rolled steel coils are very good (such as higher strength, lower yield limit, good weight deep drawing performance, etc.).
5. High-speed rolling and full continuous rolling can be realized, with high productivity.
