DC01 DC02 DC03 Hot Rolled Steel Coil Cold Drawn Steel Strip Bright And Smooth

Hot rolling takes slab (mainly continuous casting slab) as raw material, which is heated and then made into strip steel by roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature through laminar flow, rolled into steel strip coil by coiler, and the cooled steel strip coil is processed into steel plate, flat coil and slitting steel strip products through different finishing operation lines (leveling, straightening, cross cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) according to different needs of users.
Cold rolling: hot rolled steel coils are used as raw materials, and after the oxide skin is removed by pickling, cold rolling is carried out. The finished product is rolled hardened coils. As the cold work hardening caused by continuous cold deformation increases the strength and hardness of the rolled hardened coils, and the toughness and plastic index decreases, the stamping performance will deteriorate, and it can only be used for parts with simple deformation.
