The purification of molten metal plays an important role in improving the mechanical properties of castings. At present, the filtering device used to purify molten metal is mainly ceramic foam filter used for aluminium castings, which can effectively intercept harmful impurities in molten metal, convert molten metal from turbulent flow to laminar flow, and completely […]

Ceramic foam filter is a very good product, which is widely used in molten aluminum filtration in aluminum smelting and casting process to prevent particulate impurities in molten aluminum from entering the casting billet and affecting the quality of aluminum processed products. According to the quality requirements of the castings, the flow rate of the […]

Regardless of the filter used, care must be taken to ensure that the filter is not affected by excessive vibration or changes in the metal level. These interferences will cause the release of inclusions, which may eventually lead to inclusions in the finished product. Good process control downstream of the final aluminum alloy filtration equipment […]

Ceramic filters for aluminum foundry are commonly used to filter various molten aluminum. Ceramic filters for aluminum foundry formed by impregnating organic foam with an aqueous slurry, the slurry composition containing 20%-50% silicon carbide, 20-50% alumina, 1.5-5.0% aluminosilicate fibers, And it has been fired at a temperature of at least 1150°C so that the filter […]

Foam ceramic filter is the last technology for molten aluminum filtration. It is particularly important to choose the foam ceramic filter board. According to the environment of each foundry, choose the best ceramic foam filter and obtain high cleanliness of molten aluminum. The choice of foam ceramic filter plate depends on the impurity content in […]

A lot of practice shows that the use of foam ceramic filter material can remove inclusions, improve the structure of castings, improve the mechanical properties and pass rate of castings, improve the processing performance of castings and reduce machining costs. Foam ceramics have a good filtering effect and no pollution to the alloy. However, if […]

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 […]

Ceramic foam filter of aluminum is used to remove the oxide inclusions and provide high-quality molten aluminum for the casting process. Before the ceramic foam filter (CFF) filters the molten aluminum, it is necessary to fully preheat the ceramic sheet and the filter box to ensure that the molten aluminum can pass through the filter […]

Filtering of Molten Aluminum is a method of removing impurities by letting the aluminum alloy melt pass through a filter made of neutral or active materials, so as to separate solid inclusions suspended in the melt. According to the filtering properties, it can be divided into two categories. The filtering method of molten aluminum can […]

Aluminum liquid filtration generally uses foam ceramic filter filtration. When the aluminum liquid passes through the tortuous and interconnected pores in the foam ceramic, the internal debris is deposited on the wall of the pore under the action of fluid power, inertia, interception, collision, and adsorption. So that the clean aluminum liquid enters the casting […]
