Ceramic Foam Filters Foundry, Molten Metal Filters

Ceramic foam filters foundry are just developed as new type of 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 for foundry play an essential role in removing these impurities and ensuring high-quality casting.

Ceramic Foam Filters Foundry

Ceramic Foam Filters Foundry Application

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

Ceramic Foam Filters Foundry Advantages

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

The ceramic foam filters foundry have a gasket material chemically and mechanically bonded thereto. The filters have particular utility in the filtration of molten metal, especially aluminum. The filters are formed by immersing the porous filter body, in a gasketing medium consisting of a concentration of ceramic fibers, one or more binders, and the balance a vehicle such as water and applying a vacuum through the porous filter to draw the gasketing medium into contact with the portions of the filter body to be gasketed.
