Ceramic follicle foamers are only developed as a new type of molten metal filter to reduce casting defects. They play a vital role in the metal casting and foundry industries. They are used to filter out impurities in molten metal. Improve quality and performance. A "filter cake" is formed on one side of the inlet filter, and deep filtration is carried out inside the ceramic matrix, so these ceramic foam filters are an effective tool to achieve the metallurgical purity of molten metal during the casting process. The filter also stabilizes the filling of the mold, thereby preventing undesirable defects in the casting. The type of ceramic foam filter especially depends on its application requirements. Therefore, in practice, filters for filtering non-ferrous metal alloys (casting temperature up to 1000°C), filters for filtering sheet and spherical graphite cast iron, and filters for filtering steel are used. Depending on the casting material, filters based on Al2O3, SiC, ZrO2 or graphite can be used. In the ceramic industry, they are used to filter impurities in molten metal to improve the quality and performance of the final product. Ceramic foam filters require precise performance under extreme high temperatures and harsh conditions, and must meet the highest standards in terms of performance, durability and heat resistance. This is where the expertise and engineering expertise of technology bubble services stand out. As a recognized leader in engineering-based foam conversion, our products are used by some of the most well-known foundries around the world for casting aluminum, steel, iron and copper.
We can supply ceramic foam filters are as follows:
1.Silicon carbide ( SiC) is used as a distinctive element in the refractory mixture material to make foam filters. Gray in color, foam filter is a strong and durable foam filter, which can be used to purge and filter solution of ductile iron casting, grey iron and other iron casting. 2. Zirconia Ceramic Foam Filter is applied to purge and filter solution of steel high temperature metal such as steel alloy stainless steel etc.Typical application of zirconia ceramic foam filter is for in-mold, tundish, pouring cup or baffle-type filtration. 3. Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys. White in color alumina foam filter is made from high purity alumina (AI2O3). It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration.
Advantage of Ceramic Foam Filters
Simplified and shorten gating system,increasing yield.
High strength without loose ceramic particles or powder
Remove tiny slag effectively and purify molten metal.
Three dimensional connected mesh structure and high porosity
Well-distributed molten metal and improve performance.
Quiet laminar flow of molten metal.
Smaller particles are captured on the filter cake created by the larger particles , finer particles are captured within the pores in the filter.
Principle Of Using Filter: • Set the filters as close as possible of the casting. • Use simple gating system without dirt trap ( improve yield). • The working area of filter should be 4-6 times of the section of chocked flow in gating system to make sure that the pouring speed is not affected. • Select the proper filters according to types of metal and pouring temperature. • The higher porosity, the better filtration.
