ASTM DC01 SPCC Cold Rolled Steel Coil

Cold rolled steel coil for car structural parts, 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.

Chilled coil is produced from hot-rolled coil by pickling and cold rolling. It can be considered a type of cold-rolled coil. Cold-rolled coil (annealed): This is produced from hot-rolled coil by pickling, cold rolling, hood annealing, and flattening (finishing).

Cold rolled steel coil for car structural parts 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.

The company's slitting machine, slitting line, cuts ASTM JIS DC01 SPCC SPCD St12 DP1180 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.
