Color steel coil is formed into coils by hot pressing and cold pressing. In order to facilitate storage, transportation and processing, it is divided into hot-rolled coil and cold-rolled coil. Color steel coil is mainly sold to large customers,
and general users do not have uncoiler equipment or use is limited. Color steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, and facilitate various processing
(such as processing into steel plate, steel strip, etc.).
Forming coil is mainly hot-rolled coil and cold-rolled coil. Hot rolled coil is a product processed before recrystallization of billet. Cold rolled coil is the follow-up processing of hot
rolled coil. The general weight of color steel coil is about 15-30t. This year, China's hot rolling production capacity continues to expand, there are dozens of hot rolling production lines, and some projects are about to be built or put into production.
The sales of color steel coils are mainly aimed at large customers, and the general users do not have uncoiler equipment or use a limited amount.
The follow-up processing of color steel coil will be a promising industry. Of course, at present, large
steel mills have their own uncoiling and leveling projects. After heating, the strip is made from roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature by laminar flow, and then rolled into
steel strip by coiler. The cooled steel strip coil is processed into steel plate, flat coil and longitudinal cut steel strip products by different finishing lines (leveling, straightening, cross cutting or longitudinal cutting, inspection, weighing, packaging
and marking) according to different needs of users.
Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge,
construction, machinery, pressure vessel and other manufacturing industries. With the development of new technologies for controlling the size accuracy, shape and surface quality of hot rolling as well as the appearance of new products, hot rolling steel
plate and strip products have been more and more widely used and become more and more competitive in the market.
Hot rolling steel plate products include steel strip (roll) and steel plate with its shear. The steel strip (roll) can be divided into
straight hair roll and finishing roll (divided roll, flat roll and longitudinal cut roll). Main products: hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their material and performance.
According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder and pressure vessel steel, pipeline steel,
