Product Description

10ppi 20ppi 30ppi 40ppi Magnesium Oxide Molten Metal Porous Reticulated Ceramic Foam Filter For Purge Magnesium Alloy

Ceramic Foam Filter

The Alumina Ceramic Foam Filter's suitable temperature is 1000ºC, which is suitable for the over-rapid competition of aluminum and alloy dissolution efficiency.
In order to meet the increasing requirements of aluminum casting quality,it's more and more important to use the Alumina Ceramic Foam Filter.
The use of the filtration process is mainly based on the following considerations ,one side the  filtration will let the aluminum liquid to become orderly and relatively calm,on the other side,the solid slag from the metal liquid will cleaned in effective,the quality of casting will get increase quickly.
Alumina ceramic foam filter can effective clean the solid slag from the metal,so the aluminium alloy can carry out forging, aluminum foil manufacturing extrusion processing and other processes smoothly.
Alumina ceramic foam filter have the range from 10pp coarse porosity to 40pp small porosity to be selected.

Effect of Ceramic Foam Filter
Clean the metal liquid
Simplified gating system
Improve the microstructure of castings
Reduce inclusions in castings
Improve casting pass rate
Reduce internal reoxidation of castings
Reduce surface defects after casting processing
Type of ceramic foam filter
According the meterial have those type:Silicon carbide ceramic foam filter,Alumina ceramic foam filter,Magnesium oxide ceramic foam filter

Alumina Ceramic Foam Filter


Aluminum Ceramic Foam Filter are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses .With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions,reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

Silicon Carbide Ceramic Foam Filter

 

Sic Ceramic Foam Filter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages,for example, large surface area of slags collection. Large inner surface area of filtering.small flow resistance.good filtering effect.etc. SIC Ceramic Foam Filter is one of the size ,the size can be customized.

Zirconia Ceramic Foam Filter
 

Zirconia Ceramic Foam Filter is a phosphate-free, high metling point, It is characterized by high porosity and mechanochemical
stability and excellent resistance to thermal shock and corrosion from molten steel, It can effectively remove inclusions, reduce trapped gas and provide laminar flow when molten zieconia foam filtrated, it is machined to tight dimensional tolerance during production, this combination of physical properties and precise tolerance make them first choice for molten steel,alloy steel, and stainless steel, etc

How to choose the ceramic foam filter
 It's important to select a correct the type of the ceramic foam filter according the type of castings and the cast weight.General principle is the whole pouring system is a pressure free system,to make sure the metal liquid is smooth filling,the important spot is(The ratio of the cross-sectional area)
