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.
