Cold Rolled Aluminum Circle

Cold rolling production process:

Using hot-rolled steel coil as raw material, the oxidized skin was removed by acid washing, and then cold-rolling, the finished product is rolled hard coil. Cold work hardening due to continuous cold deformation increases the strength and hardness of the rolled hard coil and decreases the toughness index., therefore, the punching performance will deteriorate and can only be used for parts that are simply deformed. Rolled hard rolls can be used as raw materials for hot-dip galvanizing plants because the hot-dip galvanizing units are provided with an annealing line. The rolled hard coil weight is generally 6 ~13.5 tons, and the hot-rolled pickling coils are rolled continuously at room temperature.

Product Features of Cold Rolled Aluminum Circle:

Because it is not annealed, its hardness is very high (HRB is greater than 90), and the machining performance is extremely poor. Only a simple directional bending process of less than 90 degrees can be performed(perpendicular to the winding direction).

To put it simply, cold rolling is made on the basis of hot rolled rolls. Generally speaking, the produce process is hot rolling-pickling-cold rolling.

Cold-rolled aluminum wafers can be used in automobiles, rice cookers, washing machines, etc household appliances, as well as industrial equipment, construction materials.
 
Packaging of Cold Rolled Aluminum Circle


Usually, we have six layers of packing: put on wooden supports and put desiccant, wrap moisture proof film, wrap the plastic film, wrap the moisture-proof cotton, wrap the plastic moisture proof film again and pack it with cardboard.
