Foundrymax Square 55×55×22mm / 10PPI Zirconia Ceramic Foam Filter for Steel Casting

Foundrymax offers the 55×55×22mm square zirconia ceramic foam filter, a standard size widely used in steel foundries for filtering molten carbon steel, alloy steel, and stainless steel. This filter is engineered to deliver reliable performance at operating temperatures up to 1700°C, making it suitable for the demanding thermal conditions of steel casting.

The open‑cell reticulated network creates tortuous paths that intercept non‑metallics through mechanical sieving and surface adhesion. The result is cleaner metal entering the mould cavity, which translates to reduced scrap from inclusion‑related defects, improved mechanical properties, and better surface finish on finished components.

Why Foundrymax for This Zirconia Filter?

As a direct manufacturer with full control over sintering and quality inspection, we produce this standard 55×55×22 size with consistent pore uniformity and dimensional accuracy. Alternative thicknesses (15mm, 20mm, 25mm) and PPI grades (10, 20, 30) are available upon request to match specific steel grades and casting conditions. Our technical team can provide guidance on filter placement to ensure optimal performance in your specific application.
