The technology of removing non-metallic inclusions in the molten aluminum alloy, adopting the furnace flux treatment, and the technology of molten alu foam ceramic filter filtration outside the furnace has long become an important method for the purification of molten aluminum. Reflected in the alloying, purification, and refinement processing technology of the smelting process. The […]

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 […]

After using the ceramic foam filter for metal casting, the rectifying effect of the ceramic foam filter can be fully demonstrated. The molten metal flowing through the ceramic foam filter has a trickle and converges into the mainstream of laminar flow. The laminar flow state of molten metal fills smoothly, avoiding the secondary oxidation and […]

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 […]

In the late 1970s, the United States made a sponge-like ceramic foam filter (CFF) made of alumina and chromium oxide. CFF filter for molten aluminum not only has good purification technology, but also is easy to use. The initial pressure difference through the melt is only 100-150mm, and once it passes, it only needs to […]

The pressure drop or alternative flow reduction caused by the Ceramic Filter for Aluminium Foundry is affected by the length of the Filters, the roughness of the filter and the effective filter area. The effect of filters on mold filling behavior has been evaluated by direct observation experiments. Direct observation is a very useful way […]

Alumina foam ceramic filter plate produced by our company can effectively remove the fineness of aluminum water to reach the inclusion of micron grade, make aluminum water into stable laminar flow, and facilitate filling. It has a unique mullite corundum structure, good mechanical strength, and chemical stability, superior aluminum water scouring performance, and strict control […]

Foam ceramic filter board has advantages: high dimensional accuracy, high mechanical strength, stable chemical composition, corrosion resistance to liquid aluminum and its alloys, no phosphorus and environmental friendliness, purifying aluminum liquid, improving aluminum quality, reducing defects, reducing defective rate, reducing cost, increasing production efficiency, and using simple and flexible size from 40mm to 600mm to […]

The ceramic filter for aluminum foundry is capable of filtering metal solution slag and metal impurities far better than other filters, and its filtration has a comprehensive physical and chemical effect. Large inclusions are physically screened and retained on the surface of the filter. Due to chemical affinity, small inclusions are adsorbed on the surface, […]
