Description
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.
Functions of ceramic foam
filter
â—decontaminate the melting metal
liquid
â—Simplified gating system
â—Improve the metallurgical structure of the castings
â—Reduce imparities of the castings
â—Improve casting quality rate
â—Reduce casting internal
re-oxidation defects
â—Reduce the surface defects after machining of the
castings
Classification
1.Alumina Foam Filter
2.Silicon Carbide Ceramic Foam
Filter
3.Zirconia Ceramic Foam Filter
4.Magnesia Ceramic Foam Filter.
Guide of Choosing Ceramic Foam
Filter
It’s
very important to choose and design filter model & filter seat
correctly according to casting types and pouring weight. The
general principle is that the whole gating system should be a
system without pressure to ensure that the molten metal liquid
filling mould smoothly. Ratio of the sectional area will be the
main point.
