Ceramic Filter Portugal Aluminium can remove tiny non-metallic inclusions in the aluminum melt in the process of filtering and purifying molten aluminum.
Gently put the ceramic foam filter plate into the filter box. Then press the gasket around the filter plate by hand. Prevent lateral flow of molten aluminum. Preheat the filter box and filter plate evenly. In order to make the temperature close to the temperature of the molten aluminum. Preheating can remove moisture and facilitate rapid filtration. The preheating method can be electric heating or gas heating. Usually, the preheating time is 15-30 minutes.
Ceramic Filter Portugal Aluminium manufacturing process
The main raw material of the porous filter material is high-temperature alumina.
It does not react with molten aluminum, does not dehydrate during the roasting process, has a very small shrinkage rate, and has relatively stable physical and chemical properties.
The slurry used is mainly composed of water-suspended colloids of various components.
When making embryos, the slurry can firmly adhere to the foamed plastic screen.
When grouting, it should not be too thick or too thin. If it is too thick, the mud will not easily fill up the foam on the sieve. If it is too thin, it is easy to settle on the plastic net and form an uneven slurry.
Therefore, controlling proper moisture is the key to pulping. In addition, the adhesiveness of the slurry should be moderate. Tests have found that adding too much low-temperature binder will cause excessive agglomeration of the slurry.
Excessive squeezing of the slurry will make it difficult to recover the foam mesh.
Adding too little adhesive will result in too low bonding performance of the slurry, and the slurry will not be tightly attached to the foamed plastic net.
After dismantling, there is no power and it is easy to dismantle. Even if it has a certain strength when hung, because the slurry is too thin, the network structure is very brittle and the overall strength is poor.
The metal mesh is used to make the oven board, and the oven board is used as the support board of the foam block drying body after the slurry is placed.
Dry at room temperature first, then in hot air. Firing is a key step in the porcelain making process.
Mastering the firing changes in the high-temperature firing process and formulating the correct firing system are the keys to firing high-quality products.
Foam Ceramic Filter has excellent resistance to corrosion and corrosion of molten aluminum, can effectively remove inclusions, reduce trapped gas in molten aluminum, and provide laminar flow to make the filtered metal significantly cleaner.
Cleaner aluminum will result in higher quality castings, less scrap, and fewer inclusion defects, all of which contribute to the bottom line of profit.
