Ceramic Foam Filter Aluminium Foundry, Aluminum Melt Purification

Ceramic Foam Filter Aluminium Foundry is mainly made of impact force and chemical corrosion resistant materials, suitable for all aluminum alloy casting.

Ceramic foam filters can improve the quality of aluminum ingots and reduce the rejection rate. They can also be used in continuous casting and rolling processes and can be manufactured in all standard sizes and different thicknesses.

In the field of national defense technology such as aerospace, the application of large aluminum alloy components is more and more, and the requirements for components are higher and higher.

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

Melt purification of aluminum alloy is one of the basic guarantee measures to produce high quality aluminum castings, and also the main means to improve the comprehensive performance of aluminum alloy.

The refining effect of aluminum alloy melt has an important effect on the formation of porosity, porosity and inclusion, and directly affects the physical, energy, mechanical properties and serviceability of aluminum castings.

Aluminium Foundry Ceramic Foam Filters

Effective Ceramic Foam Filter Aluminium Foundry purification is the first prerequisite to obtain high quality aluminum alloy components.

There is no high quality aluminum alloy molten liquid, even after the metamorphic grain refinement treatment again effective, processing and forming control again advanced, high quality castings is difficult to imagine.

And once the defects exist from the beginning, even if a reasonable casting process and heat treatment process is adopted later, the defects will still stubbornly exist and be difficult to remedy.

Therefore, people attach great importance to the gases and inclusions in casting aluminum alloy melt, and take various measures to remove them.

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

There are many related researches, such as: various purification methods (physical and chemical) for degasification and slag removal of aluminum melt, various electric and magnetic field treatment methods for melt, study on the structure of alloy melt and the influence of melt thermal history on solidification structure, rapid solidification/powder metallurgy of aluminum alloy and so on.

At the same time, smelting, metamorphism and purification are still the main links causing environmental pollution in the process of casting aluminum alloy production.
