Albania China Foundry Filter can effectively remove inclusions from aluminum melt and significantly improve the quality of aluminum products. Due to the oxygen affinity of aluminum, oxides are the most common among all aluminum alloy melt inclusions.

In the modern aluminum casting industry, in the process of producing aluminum products, ceramic filter plates can effectively remove the alumina impurities in the aluminum liquid, and increase the quality of aluminum products.

If the chemical composition of the non-metallic inclusions formed in the aluminum melt is not removed, the chemical composition is very stable, and it is easy to cause cracks in the casting after solidification.

The presence of non-metallic inclusions makes it difficult to predict the mechanical properties of castings.

The influence of oxidized inclusions on the tensile properties of aluminum alloys, they believe that the main reason for the decrease in mechanical properties of aluminum alloys.

Therefore, it is very necessary for Albania Aluminium to use Albania China Foundry Filter.

Ceramic foam Filter Cff is widely used in the production of large aluminum processing enterprises in Russia, the Middle East and Southeast Asia.

During use, it is not only necessary to remove the aluminum melt inclusions, but also to avoid clogging of the Foundry Ceramic foam Filters and improve the service life of the CFF.



RUSAL engineers said

The process by which inclusions in the matrix affect the fracture of the aluminum alloy specimen can be described as

When the specimen is subjected to tensile force, severe concentrated stress occurs at the crack front edge. When the tensile stress exceeds the yield strength, plastic deformation occurs near the crack tip first, forming a plastic zone, which leads to stress relaxation and blunt crack tip.

As the plastic zone expands, the inclusions at the front end of the crack enter the plastic zone.

Because the binding force between the inclusions and the matrix is ​​relatively weak, under the action of tensile stress, the inclusions are separated from the matrix, forming the initial micropores.

Continue to increase the load, the internal necking between the crack tip and the micro-hole intensifies, causing the crack tip and the micro-hole to quickly aggregate, and the crack starts to expand forward.

Therefore, inclusions are conducive to the formation of initial micropores and have a greater impact on the propagation of cracks.

Albania is located on the west coast of the Balkan Peninsula in Southeast Europe, bordered by Serbia and Montenegro (Mondinegro) in the north, connected with the Republic of Northern Macedonia in the northeast, Greece in the southeast, the Adriatic and Ionian Seas in the west, separated by the Otranto Strait Facing Italy.

Ceramic Foam Filter Aluminium Park Korba is mainly made of impact and chemical resistant materials, suitable for all aluminum alloy castings. The ceramic foam filters can improve the quality of aluminum ingots and reduce the scrap rate. It can also be used in the continuous casting and rolling process, and can be manufactured into all standard sizes and different thicknesses.

In the field of defense technology such as aerospace, large-scale aluminum alloy components are used more and more, and the requirements for components are getting higher and higher.

In addition to ensuring its chemical composition, mechanical properties and dimensional accuracy, castings are not allowed to have shrinkage, porosity, leakage, slag inclusion and other defects.

The purification treatment of aluminum alloy melt is one of the basic guarantee measures for the production of high-quality aluminum castings, and it is also the main method to improve the comprehensive performance of aluminum alloys.

The refining effect of aluminum alloy melt has an important influence on the formation of porosity, pores, inclusions, etc., and directly affects the physical properties, performance, mechanical properties and service performance of aluminum castings.

Effective purification treatment of aluminum alloy melt is the primary prerequisite for obtaining high-quality aluminum alloy components.

Without a high-quality aluminum alloy melt, even if the subsequent grain refinement treatment of deteriorated products is effective, and the processing and forming control is advanced, it is difficult to imagine high-quality castings.

Moreover, once the defects exist from the beginning, even if a reasonable casting process and heat treatment process are adopted in the future, the defects will still exist stubbornly and it is difficult to make up.

Therefore, people attach great importance to the gas and inclusions in the cast aluminum alloy melt, and take various measures to eliminate the gas and inclusions in the aluminum alloy melt.

At present, the comprehensive treatment of aluminum alloy melt purification and homogenization refinement is considered to be a common technical basic problem that must be solved to obtain high-quality aluminum alloy.

There are many related studies, such as: various aluminum melt degassing and slag purification methods (physical and chemical), various electric and magnetic field treatment methods for melts, research on the structure of alloy melts and the melt The influence of thermal history on solidification structure, rapid solidification/powder metallurgy aluminum alloy research, etc.

At the same time, smelting deterioration and purification in the production process of cast aluminum alloys are still the main links that cause environmental pollution.

The ceramic slag is continuously lost. The inferiority of the filter plate is obvious, and the aluminum liquid causes secondary pollution.
Use open flame and electric heating to burn to red, and immediately cool to room temperature without tilting or wearing. It is said to be a good filter plate.

AdTech has a complete quality control system for ceramic foam filters, including technical standards, testing equipment and testing methods to achieve product quality control requirements.
The molten aluminum ceramic foam filter plate is a new type of filter plate made of industrial sponge as a carrier, filled with heat-resistant ceramics and then sintered.

Due to the combined action of the axial pressure, friction and surface adsorption of the molten aluminum, it is retained on the inner surface of the ceramic filter plate and the gap cavity, thereby separating the slag and the molten aluminum.

In aluminum casting production, the casting reject rate caused by casting defects such as non-metallic inclusions generally reaches 50% ~ 60% of the reject rate.
Inclusion defects not only severely reduce the mechanical properties of the casting, but also have a harmful effect on the processing performance and appearance of the casting.
Purifying liquid casting alloys and reducing or eliminating various non-metallic inclusions are undoubtedly important technical measures to obtain high-quality castings.
Since the successful development of the aluminum alloy foam ceramic filter in 1978, the foam ceramic filter technology has developed rapidly. The use of ceramic foam filter technology can effectively achieve the purpose of purifying molten aluminum alloy.

Since the waste comes from waste materials such as process waste and geometric waste in each process in the factory, the path is different, the composition is complicated, and the quality is poor.
These impurities usually generate bubbles and inclusions in the slab, which seriously affect the purity of the molten metal, which in turn affects processing performance, mechanical properties, corrosion resistance and product appearance quality.
At present, there are many ways to remove these harmful substances and purify the aluminum melt.
According to different methods, it can be divided into two types: in-furnace treatment and out-of-furnace continuous treatment (ie online treatment).

The recovery and regeneration of aluminum alloy is a very complex technical task.
Various aluminum products have a wide range of uses and are used dispersedly. How to recycle, concentrate, sort, and then realize regeneration processing is a very complex and huge project.

Monaco foundry ceramic foam filter plays a very important role in improving the quality of aluminum ingot and aluminum rod castings. It can effectively filter non-metallic inclusions in molten aluminum once or twice, thereby reducing slag holes, improving the mechanical properties of castings, and reducing processing allowances.

After the aluminum alloy material is mixed with slag, the performance of the alloy deep-processed parts will be destroyed, and the yield will be reduced, which will cause a certain economic loss.
In production, it is required to adopt the method of slag removal and filtration to eliminate the slag inclusion as much as possible.
Slag inclusions in aluminum alloy castings are one of the main factors affecting the quality of deep-processed products.
The quality of the product directly affects its market share and economic benefits.
In order to survive and develop, it is necessary to increase the added value of products and carry out deep processing.

There are many reasons for molten aluminum contamination.
1. During the smelting process, the molten or semi-melted state of the atmosphere furnace exposed to aluminum is easy to oxidize, react with water vapor and absorb hydrogen, and easily form various forms of non-metallic slag (such as lining fragments, chlorides, carbides in Changes, etc.) and coarse intermetallic particles, etc.
2. Part of the waste that constitutes the cost brings some non-aluminum impurities in the recycling process.
Because the waste comes from process waste and waste from various processes in the factory, as well as waste outside the factory, the route is different, the composition is complicated, and the quality is poor.
The above-mentioned impurities often produce bubbles and inclusions in the cast slab, which seriously affect the purity of the molten metal, and further affect the processing performance, mechanical properties, corrosion resistance and appearance quality of the product.

Monaco Aluminium uses our company’s alumina foam ceramic foam filters plate to filter molten aluminum, duralumin slag and other impurities. The ingot has been greatly reduced, the continuity of the metal has been improved, the mechanical properties have been improved, and the yield of extruded profiles has been steadily improving. , And the service life of the mold has been greatly strengthened, reduced scratches, and brought them better economic benefits.

Monaco foundry ceramic foam filter

Monaco foundry ceramic foam filter filtration and purification mechanism research
1. Through mechanical filtration, such as screening inertial impact interception, diffusion interception, friction, settlement, etc., the filtration efficiency is proportional to the mesh of the foam ceramic. The smaller the grid, the stronger the ability to intercept small particles.
2. The effect of precipitation layer or filter cake layer. With the deposition and interconnection of particles in the melt and the uneven grid supporting walls, the ability to trap foreign particles has been improved.
3. Because the surface grid frame on the rough surface formed by the gap increases the interface between the aluminum liquid stream and the ceramic solid surface, it can promote the flow of particles in the aluminum liquid stream to be more disordered, which is conducive to the capture and capture of solid particles. Deposition.
