Ceramic foam filter offers a simple, reliable, and cost-effective method to remove inclusions for Rusal foundry. Filtering with CFF is a supplement to metal treatment within the furnace, such as fluxing and degassing or inline filtration. Rusal is one of the largest aluminum production companies in the world. The company’s main products are primary aluminum, […]
The filter plate has an open-pored structure, which is characterized by having a plurality of interconnected voids, so that molten metal can pass through to remove entrained solids. Such filters include solid filter plates made of sintered ceramic aggregate. A ceramic foam filter with an open-cell structure, which is characterized by a plurality of interconnected […]
The ceramic foam is made of an open-celled, preferably hydrophobic, flexible foam material having a plurality of interconnected voids surrounded by a network of said flexible foam material. Typical materials that can be used include polymer foams, such as polyurethane foams, and cellulose foams. Generally, any combustible organic plastic foam that has elasticity and 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 […]
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 […]
