Cold -rolled plates are rolled with hot rolling rolling rolled materials at room temperature at room temperature.During the production of cold -rolled plates, because it does not heated, there are no defects such as hemp points and iron oxide skin that often appear in hot rolling. The surface quality is good and the smoothness is high.In addition, the size and accuracy of cold -rolled products, the performance and organization of the product can meet some special use requirements, such as electromagnetic performance and deep punching performance.
Cold -rolled plate density
In terms of specifications, the thickness of the cold rolling plate is generally 0.2-4mm, 600-2000mm wide, and 1200-6000mm long. The specific density density depends on the specific specifications of cold rolling plates, but there are corresponding standards.Generally speaking, the density of cold rolled plates is about 7.85g/cm3.When calculating, there is the following formula: long X wide X thick X density. Because the unit of density is gram, it is generally necessary to turn the above unit to centimeter to further compare the calculation.
What is the material of the cold rolled plate
The commonly heard of Baosteel, Angang, Bengang, etc. are the main origin of cold -rolled plates, which are divided into two types: ordinary and high -quality. Ordinary cold -rolled steel plates are mainly made of ordinary carbon structure steel or low alloy structure steel., Good quality, good stamping performance, mainly used for raw materials of plating plates in the automotive industry; high -quality cold -rolled and thin steel plates, mainly high -quality steel and cold rolled sheets, especially carbon structures, and steel plates, as well as carbon structures, and steel plates, as well as, andThe cold -rolled steel plate with deep pressure is a thin sheet with low -carbon high -quality steel 08AL, which is most commonly used for the manufacturing industry of a car dragger.Compared with ordinary cold -rolled steel plates, the quality and performance of better quality and excellent processing procedures have become necessary materials. It is essential among household appliances such as refrigerators and washing machines. It is widely used.
Cold -rolled plate specifications
Cold -rolled plate price
The common card number of cold rolling is ST12, DC01, SPCC, etc.At present, the cold-rolled rolling rolls of Lecong Market Malaysia and Ansteel are priced at 4,300-4400 yuan/ton, and Anshan Iron and Steel and Kungang Cold Rolling Plate are priced at 4400-4500 yuan/ton.
The difference between cold -rolled plates and hot -rolled plates
The difference between the two: The hot rolling of steel has good plasticity and is easy to mold. After forming, the steel has no internal stress, which is convenient for processing below.If the steel bars for building are used for stamping steel plates, the steels that need to be mechanical processing and thermal treatment are hot -rolled steel.Steel cold rolling has the characteristics of cold processing.Because cold rolling has good mechanical properties, many direct steel uses cold -rolled steel.Such as cold twisting steel bars, cold rolled wires, cold -rolled steel plates, etc.
