Ceramic Foam Filters
General Description of Ceramic Foam Filters
Ceramic filter foams is just developed as a new type molten metal filters to decrease casting flaw in recent years, play a vital role in the metal casting and foundry industries, where they are used to filter out impurities in molten metal to improve the quality and performance of the end product.
Even the slightest non-metal impurities in molten metal can have a devastating effect on the performance and strength of finished metal goods. This can result in end products failing to meet the necessary quality standards; Ceramic filters play an essential role in removing these impurities and ensuring high-quality casting.
Application of Ceramic Foam Filters
Decontaminated the molten metal liquid
Simplified gating system
Improve the metallurgical structure of the castings
Reduce slag inclusions of the castings
Increase the casting quality rate
Reduce casting internal re-oxidation defects
Reduce the surface defects after machining of the castings
Advantage of Ceramic Foam Filters
High strength without loose ceramic particles or powder
Three dimensional connected mesh structure and high porosity
Large surface area of slag collection, large inner surface area of filtering
Excellent thermal shock resistance
Various sizes, shapes and pore sizes are available
Particles larger than the pore size are captured at the top of the ceramic foam filter
Smaller particles are captured on the filter cake created by the larger particles
Finer particles are captured within the pores in the filter
