A device and method for online vacuum degassing of aluminum liquid

Background technique

The gas element in the aluminum liquid is mainly hydrogen, and its content is generally greater than 0.35ml/100g. During the solidification process of the aluminum liquid, it precipitates and forms bubbles. Once captured by the solidification front, pinholes, pores, looseness, etc. will be formed in the ingot. Casting defects lead to scrapped ingots or subsequent processing defects. According to reports, casting waste caused directly or indirectly by excessive hydrogen concentration in liquid aluminum accounts for more than 40% of the total waste. As the application scope of aluminum alloy products becomes wider and wider, the attention to the internal structure of aluminum alloy ingots has become more and more important.

Tightness requirements are also getting higher and higher. Reducing the hydrogen content in molten aluminum plays an important role in improving the quality of aluminum alloy ingots. In order to reduce the hydrogen content in the aluminum liquid, domestic aluminum processing enterprises currently use a degassing device that rotates and sprays inert gas. This type of traditional rotating spray degassing device places a graphite rotor in the aluminum liquid in the launder system and sprays the inert gas through it. The rotating graphite rotor breaks the bubbles and forms small bubbles, which increases the contact area between the inert gas and the aluminum liquid and the bubble floating time. Since the hydrogen partial pressure of the inert bubble is low, the hydrogen atoms in the aluminum liquid form hydrogen molecules and enter the inert bubble. Within, the bubbles float up and are removed to achieve the purpose of hydrogen removal. However, when domestic enterprises produce high-end aluminum alloys, they still need to mix a small amount of toxic gas chlorine into the inert gas to ensure high degassing efficiency. This poses great safety hazards and environmental pollution risks, and the hydrogen content of the aluminum liquid after degassing mainly depends on The hydrogen concentration of the incoming aluminum liquid before degassing is unstable, and the degassing efficiency of the aluminum liquid is unstable. Therefore, the incoming aluminum liquid must be pretreated before online degassing, which increases the process cost and production cycle.

Aluminum casting and forging

Aluminum casting and forging have a rich history that dates back centuries, showcasing the evolution of these manufacturing processes and their pivotal role in various industries. They form the backbone of various manufacturing operations, enabling the production of intricate components and structures that uphold the integrity and functionality of various products. 

What is the Process of Aluminum Foundry and its advantages?

The process of aluminum foundry, also known as aluminum casting, is a manufacturing method used to produce a wide range of aluminum parts and products. It involves melting aluminum and pouring it into molds to create the desired shapes. Here's an overview of the process and its advantages:

Process of Aluminum Foundry:

Pattern Creation: The process starts with the creation of a pattern or mold that represents the final product. Patterns can be made from various materials, such as wood, metal, or plastic, and they are typically shaped to match the desired part.

Mold Making: A mold is created by packing sand or other refractory materials around the pattern. This mold is made in two halves, the cope (top) and the drag (bottom). The molds must be designed to allow the molten aluminum to flow into them.

Melting Aluminum: Aluminum is melted in a furnace at temperatures exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit). Various alloys can be used depending on the desired properties of the final product.

Pouring: Once the aluminum is molten, it is poured into the mold. The mold is typically placed in a flask to maintain its shape during the pouring process.

Cooling and Solidification: As the molten aluminum cools and solidifies in the mold, it takes on the shape of the pattern. This process can be aided by cooling water or other methods to control the cooling rate and prevent defects.

Shakeout: After the aluminum has cooled and solidified, the mold is broken, and the cast part is removed. Excess material, called the casting flash, is typically trimmed or removed in this step.

Finishing: The casting may undergo additional processing steps such as machining, sandblasting, heat treatment, or surface finishing to meet specific requirements and tolerances.

Advantages of Aluminum Foundry:

Lightweight: Aluminum is a lightweight material, making it ideal for its uses where weight is a significant factor. It's commonly used in the aerospace, automotive, and transportation industries.

High Strength-to-Weight Ratio: Aluminum alloys offer excellent strength-to-weight ratios, providing structural integrity while keeping weight low.

Corrosion Resistance: Aluminum has natural corrosion resistance, which can be enhanced through various surface treatments and coatings.

Complex Geometries: Aluminum foundry allows for the production of complex and intricate parts with precise detailing.

Recyclability: Aluminum is highly recyclable, making it an environmentally friendly choice. Recycling aluminum consumes significantly less energy compared to primary production.

Thermal Conductivity: Aluminum has good thermal conductivity, making it suitable for heat exchange applications.

Cost-Effective: Aluminum foundry processes can be cost-effective for high-volume production runs due to efficient production and relatively low material costs.

Design Flexibility: Aluminum casting allows for the creation of intricate and customized designs, offering flexibility in product development.

Ductility and Malleability: Aluminum is ductile and malleable, allowing for easy forming and shaping of parts.

Excellent Electrical Conductivity: Aluminum has good electrical conductivity, making it useful in electrical and electronic applications.

It's important to note that the specific foundry process, such as sand casting, die casting, or investment casting, can affect the final product's properties and cost. The choice of process depends on the desired part, production volume, and other requirements.

Alcoa considers closing Norway's Lista aluminum smelter completely

According to foreign media reports, due to rising electricity prices, international aluminum giant Alcoa is considering closing its Lista aluminum smelter in southern Norway.

Alcoa Energy Director Ole Lofsnaes wrote in a letter to the Norwegian Ministry of Petroleum and Energy: "The Lista aluminum smelter is still struggling to make a profit, although it will reduce some capacity in 2022 due to high electricity prices. Struggles, 2024 is expected to be a more difficult year. For this reason, Alcoa is now considering all possible future scenarios for the Lista aluminum smelter, with complete closure of the aluminum smelter being one of the scenarios being considered. " Last August, when electricity prices reached record highs, Alcoa reduced some capacity at its Lista aluminum smelter. In February this year, the company announced that it would reduce the factory's production capacity by 30% throughout 2023. Alcoa Energy Director Lofsnaes said it was crucial for the company to sign a new power supply agreement as soon as possible to protect it from high spot prices in the future. The Norwegian government plans to cut carbon dioxide offsets for industrial companies starting in 2024, which will also compound the problems at the Lista aluminum smelter. It is understood that Alcoa's Lista Aluminum Smelter in Norway has an annual primary aluminum production capacity of 94,000 tons and a total of three electrolytic aluminum production lines. One of the production lines was closed last year. Alcoa also operates an aluminum smelter in Mosjoen, northern Norway, with an annual production capacity of 200,000 tons of primary aluminum. Spot electricity prices in southwestern Norway have averaged €78.79/MWh so far this year, well below the 2022 average price of €211.28/MWh but still higher than the average price in northern Norway of €26.91/MWh.
