Cold rolled iron plate / coil is one of the most commonly used steel plate materials, which can be mainly used in construction, plant, machine production and many other aspects. Although the structure of the cold rolled plate is solid and precise, we
still need to pay attention to maintenance in use to prolong its service life. Most of the cold rolled plates need to be stored in the warehouse first, when we choose to keep the cold rolled plate The site or warehouse should be located in a clean
environment, well ventilated and well drained place, and far away from the workshop which may produce harmful gas or dust.
Cold rolled iron sheet is a product made of hot rolled coil rolled at room temperature and below recrystallization temperature. It is mainly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at recrystallization temperature,
but it is generally understood as rolling with normal temperature rolling materials.
Application: automobile manufacturing, electrical products, etc
Performance, cold-rolled sheet has good performance, that is, through cold rolling, can get
thinner, higher precision cold-rolled strip and steel plate, high flatness, high surface finish, cold-rolled sheet surface clean and bright, easy to coating processing, variety, wide use, at the same time with high stamping performance and non aging,
low yield point characteristics, so cold-rolled sheet has a wide range of uses, the main purpose is to improve the quality of cold-rolled sheet It should be used in automobile, printing barrel, construction, building materials, bicycles and other industries,
and it is also a good material for the production of organic coated steel plate.
1. Cold rolled coil products are accurate in size and uniform in thickness, which can fully meet the requirements of high precision tolerance.
2. The ultra thin strip which can not be produced by hot rolling can be obtained.
surface quality of cold rolled products is superior, and there are no pockmarks, pressed scale and other defects of hot rolled coils. According to the requirements of users, the coils with different surface roughness (glossy surface or rough surface,
etc.) can be produced to facilitate the next process.
4. Cold rolled sheet has good mechanical and technological properties (such as high strength, low yield limit, good deep drawing performance, etc.).
