Tag Archives: Ceramic Foam Filters for Molten Aluminum

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 […]

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 […]

Three placement Ceramic Foam Filters for Molten Aluminum Horizontally Top-down: The best way for the molten metal to pass through the filter from bottom to top. In the initial stage of filtration, the filtered liquid has a shower phenomenon. As the liquid below fills up, the shower phenomenon disappears. Bottom-up: the filtered liquid flow without […]
