¿Cuál es la diferencia entre la bobina de aluminio laminada en caliente y en frío?

The difference between cold rolled aluminum coil and hot rolled aluminum coil is mainly due to the difference in the production process.

El laminado en frío se procesa mediante una máquina de fundición en un rodillo de fundición y un laminador en frío.. El laminado en caliente se produce por el calentamiento del lingote de aluminio.. Debajo de la fundición y colada en lingotes planos., through the milling surface, homogenized by the hot rolling mill after rolling. En segundo lugar, the difference of raw material, hot rolled billets are casting aluminum ingots – heating – rolling into roll, cold rolled billets are casting and rolling – cold rolling. Además, due to the different production processes, resulting in the performance difference between cold rolled aluminum coil and hot rolled aluminum coil. Hot rolled aluminum coil has high surface quality, while mechanical properties and ductility are strong, and oxidation effect is good. Cold rolled aluminum coil mechanical properties is relatively poor, hardness is high, so usually used for the mold.

How to identify hot and cold rolled aluminum coil

Firstly, you can generally determine by visual inspection, usually hot rolled aluminum coil’s surface is more bright.
En segundo lugar, they can be tested by the elongation, usually the elongation of hot rolled aluminum coil is higher than cold rolled aluminum coil.
Además, the difference can be seen through the crystal, hot rolling is more than 90% of the thermal deformation of the processing of the organization, and in the hot rolling process for simultaneous recrystallization, so the strip has fine grain, the performance is uniform, and cold Casting Tissue with Dust Cylindrical Distribution in Feather Shape.
