Foundry alumina ceramic foam filter products are designed to remove inclusions and reduce turbulence, so as to achieve a rapid and stable flow of molten metal, thereby improving the quality of castings. It has excellent filtering effect on all aluminum and aluminum alloys. The foundry alumina foam ceramic filter has a mesh structure, has a […]
Ceramic foam filters have become the most widely used filter material in the world’s aluminum industry, including Assan Alüminyum foundry. Assan Alüminyum, one of the world’s leading manufacturers in the flat-rolled aluminum industry, has been producing coil & sheet, foil, and pre-painted aluminum products. High-quality ceramic filters play a very important role in improving the […]
The filtering mechanism of the ceramic foam aluminum filter for foundry is a deep bed filtering mechanism. When filtering, the aluminum melt flows along the tortuous channels and pores under the action of static pressure, and the inclusions contained in it are combined with the filtering The inner surface of the medium is in contact […]
The ceramic foam molten Alu filters can effectively filter out the inclusions in the aluminum melt and the hydrogen adsorbed on the surface of the inclusions. The material of the filter mainly includes corundum microporous ceramic tube, glass fiber mesh and foam ceramics. The corundum microporous ceramic tube can filter out the oxide inclusions of […]
The final molten aluminum filtration step is usually a ceramic foam filter (CFF). This is a single-use disposable filter made of hard porous ceramic foam with strictly controlled pore size. Due to their simple operation and short-term good results, these are usually the only filtration equipment in many foundries. The three key parameters of CFF […]
The liquid metal filter was developed in the 1970s. The liquid metal purification technology was first applied to aluminum alloys. Because the melting point of aluminum alloys is low, the density of alloys and oxides are close, and inclusions are difficult to float. Inclusions are the most common casting defect. In casting production, many process […]
Aluminium is melted in a melting furnace before further processing and almost always filtration is required. The ceramic foam filter filtration method depends on the casting technique used or the treatment of the molten aluminum. It is generally believed that it is possible and beneficial only when sufficient amounts of metal are used. However, filters […]
