Cold rolled coil is hot rolled coil as raw material, at room temperature in the recrystallization temperature. Cold rolling is rolling at recrystallization temperature, but it is generally understood as rolling with normal temperature rolling material.Cold rolled coil is the coil produced by cold rolling process. The thickness of cold-rolled coil is generally between 0.1 and 8.0mm, and the thickness of cold-rolled coil produced by most factories is below 4.5mm. The thickness and width of our cold-rolled coil can be customized according to customer requirements.
1、Characteristics of cold rolled coil
1、The products produced by the cold rolling process have the advantages of clean and bright surface, easy coating, variety, wide use and so on.
2、The plate itself has the advantage of high stability, so it can maintain good performance in both short-term and long-term mechanical applications.
3、There are many specifications and varieties of cold rolled rolls. It can satisfy the different needs of customers, while also can be customized to request.
2、Cold rolled VS hot rolled
Cold rolled coil is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolled steel coil, because of rolling at room temperature, no oxide sheet. Therefore, compared with hot rolled steel coil, cold rolled coil has the advantages of good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and technological properties 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 coil.
3、Wide use of cold rolled steel coil
Cold rolled coil has good performance. Its surface finish is high and easy to be coated and plated. And this product variety, wide use, at the same time has the characteristics of high stamping performance. So the cold rolled coil has a wide range of uses, mainly used in automobiles, printed iron drums, construction, building materials, bicycles and other industries, but also the production of organic coated steel coil selection.
