Process of rolling aluminum sheet

The process of producing rolled aluminum sheet involves several steps, starting from aluminum raw material, to the final rolled sheet with the desired thickness and dimensions. The two main methods of producing rolled aluminum sheet are hot rolling and cold rolling. Here’s an overview of the process:

1. Ingot casting preparation:
The process starts with the preparation of aluminum ingots. These ingots are usually cast from molten aluminum in a mold and allowed to solidify. The composition and alloy of the ingot is carefully controlled according to the intended application of the rolled plate.

2. Homogenization (optional):
En algunos casos, especially for certain aluminum alloys, the ingot may undergo a homogenization process. This helps ensure uniformity in the material’s microstructure and composition.

3. Heating (hot rolling only):
During hot rolling, steel ingots are preheated to high temperatures to make them more ductile and easier to deform.

4. Laminado en caliente:
During hot rolling, a preheated aluminum ingot passes through a series of rolling mills, gradually reducing its thickness while extending its length. The process involves multiple passes over the rollers with gradually decreasing gaps between them.
The hot rolling process reduces the thickness of aluminum while increasing its length and width. Materials are subjected to compressive and tensile forces during rolling.

5. Recocido (cold rolling only):

Cold rolling involves passing aluminum through rolls at or near room temperature. To prevent the material from becoming too brittle and increase its ductility, an intermediate annealing step can be introduced during cold rolling.

6. Cold rolling:
The process of cold rolling is similar to hot rolling, but at a lower temperature. Through multiple passes between the rollers with gradually decreasing gaps, the material is gradually thinned and elongated.

7. Surface treatment and coating (optional):

despues de rodar, aluminum sheet may be surface treated or coated to improve its surface finish, resistencia a la corrosión, or other properties.

8. Cutting and shearing:
The rolled aluminum sheet is cut and sheared to the required size. This step ensures that the sheet is uniform in size and meets specified tolerances.

9. Quality control:
Rolled aluminum sheets undergo rigorous quality control inspections to ensure compliance with industry and customer specifications. These inspections include measurements of thickness, dimensions, mechanical properties and surface quality.

10. Packaging and delivery:
The final rolled aluminum sheet is packaged and ready for distribution to manufacturers and industries who use it for various applications such as construction, transporte, embalaje, etc.

What are rolled aluminum sheet used for?
