Ceramic Filter Jakarta Aluminum casting ceramic filter plates are mainly used in the filtration and purification process of aluminum and aluminum alloy production, and used to clean aluminum liquid, aviation alloys and other demanding products.
The quality of aluminum melt is very important, and it will greatly affect the performance of subsequent processing and the quality of the final product. Therefore, all countries in the world attach great importance to the refining of molten aluminum.
There are many reasons for aluminum pollution. On the one hand, during the smelting process, aluminum is exposed to the atmosphere in the furnace in a liquid or semi-liquid state. It is easily oxidized, reacts with water vapor to absorb hydrogen, and easily forms various non-metallic forms. slag. (Such as coating debris, chlorides, carbides, etc. in the flux) and coarse intermetallic particles. On the other hand, part of the waste in the load component contains some non-aluminum impurities during the recycling process.
These impurities are easy to produce bubbles and inclusions on the plate, which seriously affect the purity of the molten metal, and then affect the processing performance, mechanical properties, corrosion resistance and product appearance quality.
Ceramic Filter Jakarta Aluminum can effectively remove a large amount of impurities in molten aluminum, as well as small inclusions in molten aluminum that cannot be achieved by conventional processes. At the same time, because the filter plate filters out fine inclusions, reduces the number of effective crystal nuclei in the molten aluminum, allows the molten aluminum to grow under large cooling conditions, shortens the solidification time, and refines the microstructure.
The ceramic foam filter plate reduces the hydrogen content in the molten aluminum. Hydrogen atoms can be adsorbed on some oxidized inclusions, and the oxidized inclusions can become the core of bubble growth, thereby filtering out the inclusions and removing other gases.
The ceramic foam filter plate removes harmful elements (Na, K) in molten aluminum through adsorption.
Ceramic filter plates for casting are suitable for the production of high-quality and demanding aluminum and aluminum alloys. Through physical adsorption and chemical action, it can effectively remove various oxide inclusions produced in the aluminum smelting process, thereby reducing casting defects and improving the quality of subsequent castings. Deep processing can provide high-quality materials.
