Rolling plate belongs to a type of steel plate, which is actually a thin steel plate that is long, narrow, and supplied in coils,
The roll and tablet are almost a cut packaging
Cold hard coil is obtained from hot-rolled coil after acid washing and cold rolling. It can be said to be a type of cold-rolled sheet and coil.
Cold rolled coil (annealed state): Hot rolled coil is obtained by pickling, cold rolling, batch annealing, leveling, and finishing.
There are three main differences between the two:
1. In terms of appearance, the cold and hard rolling board is generally slightly dull.
2. Cold rolled sheets have better surface quality, structure, and dimensional accuracy than cold rolled sheets.
3. In terms of performance, the cold and hard coils directly obtained from the cold rolling process of hot rolled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, which is "hard" externally, so they are called cold and hard coils.
Therefore, yield strength: Cold hard rolled sheets are greater than cold rolled sheets (in the annealed state), making cold rolled sheets (in the annealed state) more conducive to stamping forming.
The default delivery status for cold-rolled sheets and coils is annealing.

Rolled coil (annealed state): It is made of cold and hard coil by bell type annealing before rolling. After annealing, the work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced close to that before cold rolling.
Cold rolled sheet and coil are made from hot-rolled coil as raw material and rolled below the recrystallization temperature at room temperature, including plate and coil. The delivered pieces are called steel plates, also known as box plates or flat plates; Steel strips, also known as rolling plates, are long and delivered in coils.

Product Application
Cold rolled coils have a wide range of applications, such as automotive manufacturing, electrical products, locomotives and vehicles, aviation, precision instruments, food cans, etc. Cold rolled steel sheet is the abbreviation for ordinary carbon structural steel cold rolled sheet, also known as cold rolled sheet, commonly known as cold rolled sheet, and sometimes mistakenly written as cold rolled sheet. Cold plate is a steel plate made of hot-rolled ordinary carbon structural steel strip, which is further cold-rolled to a thickness of less than 4mm. Due to the fact that rolling at room temperature does not produce oxide scale, the cold plate has good surface quality and high dimensional accuracy. In addition, annealing treatment results in better mechanical and technological properties than hot-rolled thin steel plates. In many fields, especially in the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin steel plates.
