Learn about the standard and quality aluminium billet production process

Aluminium billets are aluminium materials used to produce a variety of aluminium products in both industrial and daily life applications. To produce high-quality aluminium billets, manufacturers must be meticulous in each stage, especially in the careful selection of raw materials. So what is the specific aluminium billet production process? Let’s explore it with Dinostar Aluminium in the article below.

1. Aluminium billet production process

1.1. Step 1: Check the raw materials

In any production process, the first step is crucial to the success of the final product, which is selecting the raw materials. For the aluminium billet production process, the raw material is the primary aluminium ingot.

At this stage, the manufacturer will randomly select pure aluminium ingots from the batch of ingots imported to test the aluminium content in the laboratory. The batches of ingots meeting the order specifications will be put into the melting and alloying stage, which requires high purity to ensure that when they come out of the furnace, the aluminium billets meet the quality standards suitable for all user needs.

1.2. Step 2: Melting and Alloying

After selecting the standard aluminium ingots, they are then placed into the melting furnace at temperatures ranging from 660°C to 710°C. This stage transforms the aluminium from solid to liquid form. Subsequently, pure aluminium is blended with various alloys such as silicon, magnesium, manganese, copper, zinc, chromium, etc., according to international alloy standards, to create aluminium alloys to meet the manufacturer’s requirements such as A6063, A6061, A6005A, A6060, Series 7000, etc. At this stage, aluminium water samples are repeatedly analyzed to ensure the absolute accuracy of the alloy composition.

1.3. Step 3: Aluminium Billet Casting

From the liquid form of the aluminium alloy, it is further passed through the GBF system and poured into the casting mold, then cooled to solidify. From this, aluminium billets in standard lengths and diameters are produced. Subsequently, the aluminium billets undergo ultrasonic testing to detect and remove any substandard products during the casting process. At this stage, the surface quality of the aluminium billets needs to be shiny and smooth to facilitate the production of other high-strength aluminium products.

1.4. Step 4: Cutting the finished aluminium billet

Depending on the intended use and specific requirements of the users, the finished aluminium billet will be cut to certain dimensions and diameters. Typically, the length will be 6,300 mm, and after cutting, it will be reduced to 6000mm to meet domestic demand. For exports, the length of both ends of the aluminium billet will be further cut to 5800mm to fit the container area. For aluminium billets with even shorter lengths, the cutting machine will automatically adjust to ensure uniform dimensions.

1.5. Step 5: Homogenization

The final step is to transfer the aluminium billets to the homogenization treatment furnace. They are heat-treated for a certain period to enhance their physical properties, improve the uniformity of chemical elements in the aluminium billets, and refine the surface quality of the finished aluminium billet. Thus, the final product is completed to the highest standard, ensuring absolute satisfaction when reaching the hands of users.

1.6. Step 6: Quality Inspection

This process is crucial in determining whether the product can be brought to market. Tests on physical properties, surface characteristics, etc., are conducted to ensure that the product meets the technical requirements when reaching the hands of users. Products that do not meet the requirements will be rejected, while those that meet the quality standards will proceed to the packaging process and be delivered to customers.

2. Address of standard and reputable aluminium billet production

Choosing a standard and reputable aluminium billet production address in today’s market is not easy. Therefore, you should thoroughly research information about aluminium billet manufacturers to make the right choice.
