Zirconia ceramic foam filters are high-performance porous refractory elements designed for molten-steel filtration. Engineered for use with unalloyed, low-alloy, stainless and high-alloy steels (service up to 1700°C), these filters remove non-metallic inclusions, promote laminar flow, and help reduce entrapped gas — producing cleaner metal and higher-quality castings with fewer defects and less scrap.
Key benefits
- Excellent chemical and thermal resistance to molten steel and aggressive alloy melts
- Effective capture and retention of inclusions and slag particles
- Promotes laminar flow to reduce turbulence and re-entrainment of impurities
- Helps reduce gas-related defects and improves final casting integrity
- Contributes to lower scrap rates and improved downstream processing yields
Typical applications
- Molten steel filtration in foundries and steel plants
- Use in refining and casting operations where high-alloy or stainless steels are processed
- Suitable for processes demanding high cleanliness and low inclusion levels
- Also employed as catalyst carrier media in air treatment applications where ceramic foam structures are required
Product notes
- Rated for continuous exposure to molten steel temperatures up to approximately 1700°C
- Supplied in foam block shapes and sizes to fit gating systems or filtration housings; pore structure and nominal porosity vary by grade (select grade based on alloy type and required filtration fineness)
- Integration with existing tundish/ladle/mold filtration systems may require sizing or mounting adaptors
For specification-driven purchases, request detailed grade data (porosity/PPI, mechanical strength, recommended maximum service temperature for specific alloys) and sample testing in representative process conditions.
