Aluminum plate manufacturers talk about aluminum manufacturi

    About aluminum, we should first think of the cold rolling process. The rolling process below the recrystallization temperature of metals and alloys is called cold rolling. (Aluminum plate manufacturers)Cold rolling, although due to metal deformation heat and friction heat, but also make the rolling temperature, has a certain role in recovery, but in the cold rolling process plays a major role is cold hardening (work hardening).

    Compared with the hot-rolled cold rolling(aluminium sheet plate) is the main feature is the thickness of the thin strip can be obtained. The thickness of the hot-rolled slab is usually 6 to 8 mm. The minimum thickness is 2.5mm-3.0mm. It is difficult to continue rolling to a thinner thickness due to the large temperature drop of the rolled material during the hot rolling and the cold rolling can easily make the rolling thinning possible. Typically, the cold rolling mill can be rolled to 0.5-4.5mm, more advanced cold rolling mill, can be rolled out of the thickness of 0.1mm-0.2mm of special thin or thick foil.

    Compared with the hot-rolled cold rolling(aluminium sheet 5083) is the main feature of the size can be rolled out of precision, uniform thickness, flatness and surface gloss, product performance and good surface quality of the product. Because the cold rolling mill has higher precision than the hot rolling mill, the comprehensive automatic control level of the cold rolling(aluminium sheet in china) mill is high, for example, the advanced cold rolling mill is equipped with such devices as thickness and plate type automatic control. In addition, the use of higher cold-rolled roll can roll out a high surface quality and mirror aluminum and so on.
