Ceramic Filter for Aluminum Foundry -sales@aluminiumceramicfiber.com

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, sidewall, or hole of the filter. Therefore, it can effectively filter out impurities of various sizes, including impurities much smaller than the filter hole. The ceramic foam filter for aluminum can also make the turbulent flow of molten metal smooth, reduce turbulence, and make molten metal flow smoothly and neatly.

Ceramic Filter for Aluminum Foundry

Ceramic filter for aluminum foundry can greatly reduce impurities. It not only can reduce the appearance of castings after demolished, but also can reduce the occurrence of defective products, and even reduce maintenance work. By using a molten metal filter, various impurities in the melt can be removed and purified. This kind of casting has a variety of alloys, which can improve mechanical properties, fatigue strength, reduce processing costs, shorten processing time, improve machinability and prolong the service life of machining tools.

The ceramic foam filters should be chosen according to the type and pouring temperature of the casting alloy, and should be used in the temperature range. The appropriate hole density should be selected, which is an important parameter affecting the purification effect and casting filling. The size of the filter should be selected reasonably and the pouring time should not be prolonged. The filter should be as close to the cavity as possible to reduce the formation of secondary oxide slag.

The ceramic filter’s ability to pass through molten metal is limited, and it should not be used beyond the limit, which will increase the chance of filter damage and affect the purification effect. The pouring temperature should try to use the upper limit of the process to increase the fluidity of the metal.

When using a ceramic foam filter, the pore size of the filter should be determined according to the quality requirements of the castings and the number of inclusions in the molten metal. The size of the filter should be determined according to pouring speed and pouring weight. In order to ensure the filtering effect of the filter, the placement of the filter and the design of the door control system should also follow the specifications.
