Ceramic Filter Portugal Aluminum is used to remove entrained solids from molten aluminum alloys before casting. When the molten aluminum is solidified, when these inclusions appear in the final cast product, they will cause the ductility of the final aluminum product to decrease or the trimming characteristics of the final aluminum product to be poor. Therefore, it is important to remove the entrained solid from the molten aluminum before casting the molten aluminum into a solid.
The filtration result of Ceramic Foam Filter Filtration depends on the chemical composition of the inclusions in the melt, the shape of the ceramic foam filter plate, the size of the filter plate, the metal flow rate, the wettability of the surface of the filter plate to aluminum, and the size of the inclusions.
Ceramic Filter manufacturer AdTech develops and produces CFF for aluminum, which is widely used in the aluminum casting industry.
With the development of science and technology, industrial production has higher and higher requirements for the purity and quality of aluminum and its alloy materials.
The traditional refining and degassing process cannot remove the fine suspended non-metallic inclusions in the molten aluminum.
Therefore, many purification methods have been studied. According to its different mechanisms and forms, purification methods can be divided into adsorption purification, physical purification and filtration purification.
Aluminum alloy is easily inhaled and oxidized during the casting process.
Therefore, there will be different degrees of gas and various non-metallic inclusions in the melt, causing defects such as looseness, pores and inclusions in the aluminum ingot.
Significantly reduce the mechanical properties, processing properties, fatigue resistance, erosion resistance, and anodic oxidation properties of aluminum, and even lead to product scrapping.
In order to reduce the influence of gas and non-metallic inclusions, people have put forward strict requirements on the raw materials and smelting process of alloy preparation on the one hand.
With the development of science and technology and industrial production, especially the rapid development of aerospace, missile, aviation and electronic technology, the quality requirements of aluminum alloys are becoming more and more stringent, and most of the deformed aluminum alloy materials.
The purification of aluminum alloy solution has become an extremely important part of the aluminum alloy production process. Advanced aluminum liquid purification technology is of great significance for ensuring the metallurgical quality of aluminum alloy and improving the final performance of the product.
Ceramic Filter Portugal Aluminum is a Filter Liner installed between the furnace mouth and the manifold.
The closer the filter box is to the manifold, the better. The reason is that the flow distance of the filtered aluminum liquid can be shortened, thereby reducing or avoiding the regeneration of oxides.
The molten aluminum flows out from the furnace mouth through the filter box, and then flows into the distribution plate through the flow trough. When the filtering device is activated, the drop before and after the melt filtering is approximately 30 mm.
With the extension of the filtration time, the inclusions on the surface of the filter plate and the hole wall increase, the filtration flow decreases, and the front and rear drop increases, and the drop increases to 50~100mm at the end of pouring.
Ceramic fiber filtration technology is one of the filtration technologies that has developed rapidly in recent years.
Compared with the traditional particulate filter material, the fiber filter material has a larger specific surface area, has a larger interface adsorption and can retain suspended solids, and has a good filtering effect.
Compared with organic fiber filters, ceramic fibers have good thermal stability, chemical stability and thermal shock resistance.
