Semi-continuous casting is often used to cast deformed aluminum alloy liquid into flat ingots and round ingots. Aluminum melt purification technology mainly uses flux purification to remove harmful impurities in the melt, such as H and Al2O3. The aluminum melt purification technology mainly divided by H mainly includes bubble float method, vacuum treatment method, ultrasonic […]

Ceramic foam filter board not only can effectively eradicate the chunk of oxide inclusions in aluminum liquid, but also can filter out the powerless small inclusion of a few microns. Because the inclusions easily absorb hydrogen atoms, sodium, potassium, and other harmful ions adsorption, and inclusion forms bubble. So the filtering of inclusions also can […]

The foam ceramic filtration mechanism is generally described as diffusion interception and inertial collision interception or screening, sedimentation and deep bed filtration. The State Key Laboratory of Tsinghua University established a three-dimensional physical model and a two-phase flow model for the filtration mechanism of foam ceramics, and carried out simulation calculations, which is very helpful […]

When choosing Ceramic Foam Filters China, you should also watch the color, take pictures, and burn the objects. ①The color is pure and free of impurities, indicating that the material is uniform. The hands are not sticky, indicating that the surface is not sprayed with adhesive and will not cause secondary pollution. ②Holding the Ceramic […]

Molten aluminium Filtration filtration mechanism Sieving Like a sieve, it prevents the inclusion of particles and their agglomerates whose size is larger than the pore size of the filter surface. Cake filter After sieving, many inclusions larger than the ceramic foam filter hole are captured at the inlet of the filter. As the number of […]

Function of Molten Aluminum Ceramic Foam Filter: Removal of impurities Purify the aluminum alloy liquid, the viscosity of the aluminum alloy liquid decreases after filtration, and the fluidity of the aluminum alloy liquid increases by 10%-15%. Therefore, filtration improves the filling capacity of aluminum alloy liquid. The flow of the aluminum alloy liquid before filtration […]

Selection of Ceramic Filter Media for Aluminum size 1. Calculate the minimum cross-sectional area of the sprue. 2. Calculate the sum of the cross-sectional area of the runner and the sum of the cross-sectional area of the inner runner. 3. Determine the placement and number of filters. 4. According to the filtering speed of the […]

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 […]

Foam Ceramic Filters for Casting removes non-metallic inclusions in the aluminum alloy melt and adopts furnace flux treatment. The technology of ceramic foam filtration outside the furnace has long become an important means of purifying molten aluminum. Reflected in the alloying, purification, and refinement processing technology of the smelting process. The smelting of aluminum alloy […]

According to different raw materials, ceramic foam filters mainly include Silicon Carbide Ceramic Foam Filter, Alumina Foam Ceramic Filter, Zirconia Ceramic Foam Filter. Silicon Carbide Ceramic Foam Filter Silicon Carbide Ceramic Foam Filter products are mainly used for filters of ductile iron, gray iron and other castings. It can effectively remove large inclusions in molten metal and […]
