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. 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.
Functions:
*Decontaminate the melting metal liquid
*Simplified gating system
*Improve the metallurgical structure of the castings
*Reduce imparities of the castings
*Improve casting quality rate
*Reduce casting internal re-oxidation defects
*Reduce the surface defects after machining of the castings
Classification:
*Alumina Foam Filter
*Silicon Carbide Ceramic Foam Filter
*Zirconia Ceramic Foam Filter
*Magnesia Ceramic Foam Filter
