Detailed Product Description
|
Zhengde Cold rolled steel coil is made from hot-rolled steel coil
as raw material, which is subjected to acid washing to remove oxide
skin and then subjected to cold continuous rolling. The finished
product is rolled hard coil. Due to the cold work hardening caused
by continuous cold deformation, the strength and hardness of the
rolled hard coil increase, and the toughness and plasticity index
decrease. Deep processing requires annealing treatment. Due to the lack of heating during the production process of cold rolled steel coils, there are no defects such as pits and oxide scales that often occur during hot rolling. The surface quality is good and the smoothness is high. Moreover, the dimensional accuracy of cold rolled steel coils is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic performance, deep drawing performance, etc.
High precision Compared to hot-rolled steel plates, cold-rolled steel coils have more precise thickness, smooth and beautiful surfaces, and also possess various superior mechanical properties, especially in terms of processing performance. Due to the brittleness and hardness of the cold rolled coil, it is not suitable for processing. Therefore, in general, cold rolled steel plates require annealing, pickling, and surface leveling before being handed over to the customer. Extensive use Cold rolled steel coil, with a smooth surface and excellent processing, is used in household appliances such as automobiles, refrigerators, washing machines, as well as industrial equipment and various building materials. With the development of the economy, cold rolled steel plates have become a necessary material in modern society. Among them, cold rolled hard coils can be used as raw materials for hot dip galvanizing plants, as hot dip galvanizing units are equipped with annealing lines. The weight of the rolled hard coil is generally between 8-23 tons. Strict craftsmanship Cold rolled steel coils generally use hot-rolled strip steel with a thickness of 1.5-6 mm as the cold rolled billet. The main processes include pickling, cold rolling, degreasing, annealing, leveling, and shearing (cross cutting, longitudinal cutting). If producing coated plates, there are also plating or coating processes such as electroplating tin, hot tin coating, and hot zinc coating. The production process of cold rolled billets is as follows: hot rolled sheet coils (raw materials) - acid washing - cold rolling - degreasing - annealing - leveling - shearing - finished product delivery. Provide deep processing The company's slitting machine, slitting line, cuts cold rolled steel coils into strips of various widths as needed, and then folds the strips into small coils for use in the next process. It is a necessary equipment for precision cutting of transformers, motor industries, and other metal strips. It is mainly used for strip cutting of materials such as tinplate, galvanized iron, silicon steel sheet, cold rolled strip, stainless steel strip, aluminum strip, steel strip, and other coils. Quality first: production and inspection in strict accordance with production standards; Price advantage: discounts based on real market prices; Transaction security: There will be no loss of customer funds; After-sales guarantee: the customer's problem is our problem; Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
