Cordierite Extruded Honeycomb Ceramic Filter for Molten Metal Filtration
Description :
The extruded Honeycomb ceramic filter is a fine strainer with straight hole structure.Honeycomb ceramic filter is mainly used for filtration of molten metal in metallurgy and foundry industry, to purify metal liquid and reduce non- metal impurity and gas, make the metal liquid to remain calm and reduce the swirl. We can produce different size and shape of extruded ceramic filter.
Product Features:
1. Purify metal liquid; get rid of non- metal impurity and gas.
2. Make the metal liquid flowing at stable speed and reduce the swirl.
3. Simplify the gating system and improve the producing rate.
4. Reduce the bubbles in casting and optimize metal structure.
5. Improve surface quality and mechanical performance of casting.
6. Reduce the rejection rate of casting, prolong the casting working life and reduce casting cost.

FAQ - Cordierite Extruded Honeycomb Ceramic Filter for Molten Metal Filtration
It's a ceramic filter with a honeycomb structure of parallel channels, used in metal casting to purify molten metal. It removes oxides, slag, and inclusions, reduces casting defects (porosity, cracks), and converts turbulent flow into smooth laminar flow.
| Advantage | Benefit |
|---|---|
| High thermal shock resistance | Withstands rapid temperature changes without cracking |
| Low thermal expansion | Reduces stress from thermal cycling |
| Chemical inertness | Won't react with molten metals, preventing contamination |
| Cost-effective | More affordable than silicon carbide alternatives |
Working temperature range: 600°C to 1600°C, depending on the metal.
| Parameter | Typical Value |
|---|---|
| Channel density | 100–300 CPSI |
| Porosity | ~59% |
| Compressive strength | Up to 69 MPa |
| Softening temperature | >1250°C |
| Sizes | 25–200mm; thickness 12–22mm |
| Shapes | Round, square, rectangle |
- Aluminum casting – removes oxides and dross
- Steel & iron casting – removes slag and inclusions
- Copper & brass casting – achieves high-purity castings
- Investment casting – clean pours for aerospace, automotive, medical parts
