Ceramic Foam Filters for Aluminum-sales@aluminiumceramicfiber.com

The biggest cause of casting defects is the mixing of impurities (including dross, slag, metal oxides, reaction products of inoculants and spheroidizing agents, casting sand, etc.). The use of ceramic foam filters for aluminum can greatly reduce such impurities, not only can reduce the appearance of castings after demolding, but also reduce the production of defective cutting products, and even reduce repair operations.

Ceramic Foam Filters for Aluminum

The use of ceramic foam filters can be said to be “a revolution in the design of casting solutions.” In other words, the countermeasures to prevent the intrusion of impurities into the mold are mainly to work on the gating system. In particular, sometimes it is unavoidable that the pouring system is complicated and enlarged due to the crossover and lengthening of the pouring system, which inevitably leads to low utilization of casting materials. However, the ceramic foam filter for aluminum can effectively remove impurities, so the pouring system only needs to ensure its function of diversion and distribution of molten aluminum, which can simplify the design of the pouring system, improve the utilization rate of molten aluminum, and increase the utilization rate of casting materials.

By using the filter, various impurities in the melt are removed and purified. Such castings have multiple alloys, which can improve mechanical properties, fatigue strength, reduce processing costs, shorten processing time, improve machinability, and extend the service life of processing tools.

Ceramic Foam Filters for Aluminum Uses

  • The working area of ​​the filter should be 4-6 times the blocking cross-section of the pouring system to ensure that the pouring speed is not affected.
  • Can not use filters to control the pouring speed.
  • Try to avoid metal liquid directly impacting the filter, and the pouring height should not exceed 300mm when directly impacting the filter.
  • The filter should be protected from moisture during transportation and storage and should be stored in a dry environment. The filter is a fragile product, so handle it with care to prevent bumps.
  • Please use compressed gas to blow off the scum generated during transportation.
    When the filter is used for the first time or the process is changed, the filtering capacity of the filter should be carefully reviewed, and then transferred to normal production after a small test.
