Ceramic Foam Filter Description:
Ceramic Foam Filter is a porous material with a high-temperature properties. Its diameter from the nanometer to the micron range, porosity is from 20% to 95%, and the use of a temperature can reach up to 1600° C.

Specifications
1. Usable at high temperature, high strength
2. Erosion resistance, minimal volume change
3. Effectively filter out impurities

Production process
*three-dimensional network structure and connected pores organic foam
*using four correction center distance and automatic extrusion
*1320 ° C Drying and solidification

Application
*effectively remove and absorb impurities
*improve the surface quality, product performance and microstructure effectiveness.
*mainly used in the domestic, construction, electricity, condensing tubes, cable and other aluminum alloy precision casting.

Usage process
*Clean the aluminum filter box, keep it clean and intact
*Put the ceramic foam filter into filter box carefully, press Sealing gasket around, avoid molten aluminum Dispersing orfloating away.
*Preheat filter box and ceramic foam filter evenly 15-30min, preheating temperature should surpass 460° C. Expansion cotton will seal after heating
*Observe change of molten aluminum pressure, control the flowing molten aluminum needed, normal start pressure: 100-150mm. The pressure falls down bellow 75-100mm when molten aluminum flowing, it will grow later.
*Do not shock and beat ceramic foam filter in filtration. Control molten aluminum flow rate in launder.
*Take out ceramic foam filter and clean filter box after filtration.

Merits:
*Easily installed
*Resistant to molten aluminum
*Non-wetting
*Excellent hot strength
*Dimensionally stable
*Suitable for both horizontal and vertical placement
