01 4月 Ceramic Filter
Ceramic Filter uses three filtering and purification mechanisms: mechanical retention, scum rectification and deep adsorption, which can effectively filter out large inclusions in molten aluminum and small suspended inclusions as small as tens of microns.
With the efforts of many foundry workers and researchers, the application of Ceramic Filter has been greatly developed.
However, it has high strength, high porosity, good thermal shock resistance and corrosion resistance to molten metal.
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 alloy 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 can melt the molten metal into a smooth, uniform and clean liquid after passing through the honeycomb holes.
The unique honeycomb structure can adsorb some small particles on the surface.
Remove impurities that cause surface problems, low strength and hardness.
Such as some non-metallic particles, slag, refractory fragments, etc., the stable metal laminar flow makes the filling effect better.
On the one hand, the bubbles overflow, on the other hand, it reduces the erosion of the sand mold and reduces the scrap rate of the product.
It can effectively remove non-metallic inclusions in liquid metal, improve the structure and mechanical properties of castings, produce high-quality precision castings, reduce casting scrap rate, and reduce tool wear during casting processing.
The foam ceramic casting filter has significantly improved economic and social benefits.
Ceramic Filter transforms the aluminium liquid from a vortex into a stable constant current, stabilizing the pure metal liquid.
Not only the molten metal is uniform, but the sealing performance of the casting is improved, the elongation of the casting is increased (increased by about 25%), the tensile strength is improved, and the surface finish is relatively improved.
After cleaning the inside of the casting, the processing time and tool damage of the casting are relatively reduced, and the production efficiency is significantly improved.
