Molten Aluminum Filter Nadvoitsy Aluminium captures aluminum dross from molten aluminum. This ability is important for maintaining the purity of the ingot during the solidification of the metal. In this way, the quality and productivity of downstream processes such as forging, extrusion and rolling can be guaranteed.

Adtech has always been committed to ensuring that customers can use the highest technology available on the market to produce the highest quality aluminum ingots, aluminum plates, etc. Our technology guarantees the adaptability of casting quality to the most important application areas of the final product.

Molten Aluminum Filter Nadvoitsy Aluminium can remove impurities in molten aluminum in the form of inclusions, which are not removed during the refining process. In order to obtain modern metal raw materials for thin wafer manufacturing, fine wire drawing, and precision casting, it is usually necessary to pass molten metal through a filter to remove these inclusions.

In particular, molten aluminum often contains entrained solids that are harmful to the final cast metal product. These entrained solids appear in the final cast product as inclusions after the molten metal is solidified, and cause the ductility of the final product to decrease or the smoothness and anodizing characteristics of the final product to be poor. Inclusions can come from multiple sources. For example, inclusions may originate from a surface oxide film, which is broken and entrained in the resulting molten metal. In addition, inclusions may come from insoluble impurities, such as carbides, borides, etc., or corroded refractory furnaces and tanks.

Nadvoitsy Aluminium said that Molten Aluminum Filter is very important for purifying aluminum melt.
The so-called purification treatment is to adopt various measures to reduce the undesired gas and solid matter in the aluminum melt to the allowable range to ensure that the performance of the material meets the standard or some special requirements.

Filtration is to use filters to filter.
When the alloy solution flows through a filter with straight holes or a filter with a three-dimensional mesh, the inclusions in the melt with a particle size larger than the mesh size are blocked by the filter, and the inclusions with a particle size smaller than the mesh size are blocked by the skeleton of the filter. And the inner surface of the channel is adsorbed.
When the alloy solution flows through the filter mesh and inner channel, the flow rate is reduced and is divided into countless small liquid streams, which tends to be laminar, thereby increasing the chance and speed of floating.
With the continuous accumulation and precipitation of adsorbents, the mesh size of the filter becomes smaller, so the particle size of the inclusions that can be adsorbed also becomes smaller, thereby improving the filtering effect.
Currently, the commonly used filters include glass fiber filters, ceramic plates, ceramic tubes, and foam ceramic filters.

RUSAL United Company is one of the large and thriving large companies in Russia and one of the leading companies in the world’s aluminum industry. It also raises funds through the shareholding of Russian companies participating in the company’s production process. After completing this grouping process, it has developed into a The world’s second largest primary aluminum producer outside of Weiqiao, Shandong, China, accounts for 6% of global total output. Except for the Chinese market, Rusal accounts for 12.9% of the world’s other markets. It is such an industry giant. The United States has a monopoly. Sanctioned it in the name of Global Aluminum.

Rusal is worried that production will be suspended due to the US sanctions, and since 80% of Rusal’s total production is used for export, this situation is disastrous for all Rusal’s plants worldwide, as well as for the global aluminum market. A blow.
Under constant pressure from the United States, not only did the United States refuse to allow their products to enter their country, the European Union also began to restrict imports of the company’s products.

Rusal was forced to make concessions and asked the chairman of Rusal to give up control of the company, but did not sell its shares. However, the United States remained indifferent and was forced to find the troubles of Rusal. The Russian aluminum giant decided to smash the pot and put forward two plans. If the United States continues to impose sanctions on the company, either they will be acquired by Russia, nationalize the company and become another weapon of the Russian government, or sell the company to China.
