ADCERAX® Silicon Carbide Ceramic Foam Filter User Guide for Reliable Casting Performance

The ADCERAX® Silicon Carbide Ceramic Foam Filter requires proper handling, preparation, and operation control to achieve stable melt filtration results. This guide helps casting engineers and operators understand the essential precautions and best‑practice steps that ensure consistent performance, long service life, and predictable behavior in demanding molten‑metal environments.

• Preparing the Silicon Carbide Ceramic Foam Filter Before Casting

  1. Inspect the filter packaging and ensure it remains fully intact before opening, as clean and uncontaminated pores support more consistent melt flow.
  2. Keep the filter in a controlled environment away from moisture or dust to maintain stable pore functionality during preheating.
  3. Position the filter correctly within the gating layout, confirming full surface contact so that metal flow enters evenly across the entire filter face.

• Preheating Procedures for Stable Melt Flow

  1. Gradually warm the filter to prevent sudden thermal exposure, as smooth temperature transitions help reduce thermal stress during the first pour.
  2. Use a heating range that aligns with the casting process so the filter reaches a thermally balanced state before molten metal arrives.
  3. Maintain proper ventilation around the heating zone to protect workers and ensure consistent air‑to‑surface temperature equilibrium on the filter.

• Operating Guidelines During Molten Metal Pouring

  1. Control the metal head height so that no excessive pressure compromises filtration uniformity or impacts pore performance.
  2. Monitor impurity load in the molten metal, adjusting flow rate when necessary to maintain effective slag interception across prolonged pouring cycles.
  3. Keep the pouring rhythm stable, as significant fluctuations can disrupt flow consistency and reduce the filter’s inclusion‑capture efficiency.

• Post‑Casting Handling, Cleaning, and Storage

  1. Allow the filter to cool naturally after casting so thermal gradients do not cause structural shock or affect repeatable performance.
  2. Dispose of used filters according to plant safety protocol, especially when accumulated slag may still retain residual heat.
  3. Store unused filters in sealed cartons placed on elevated racks to prevent moisture absorption and maintain pore stability for future batches.

Technical Insight FAQs for ADCERAX® Silicon Carbide Ceramic Foam Filter

1. Q1: How does the Silicon Carbide Ceramic Foam Filter maintain stability during high‑temperature steel and iron pouring?
   The filter uses a SiC ceramic matrix that provides thermal integrity up to 1500°C, preventing deformation or cracking when exposed to rapid temperature changes. Its structure allows controlled heat absorption, reducing thermal shock during the first metal contact. This ensures predictable performance throughout heavy‑load casting cycles. As a result, foundries gain more consistent filtration behavior and fewer heat‑related failures.

2. Q2: How does the Silicon Carbide Ceramic Foam Filter reduce turbulence in gating systems?
   The interconnected foam structure slows melt entry and converts irregular flow into more uniform laminar movement, improving the stability of the metal stream. This reduces turbulence‑driven oxide breakage and slag release that often contaminate mold cavities. By stabilizing flow behavior, the filter helps minimize defect clusters. This results in castings with more uniform internal density and fewer machining issues.

3. Q3: What role does pore uniformity play in filtration efficiency for the Silicon Carbide Ceramic Foam Filter?
   The controlled 10/20/30/40 PPI pore layout captures inclusions while maintaining consistent flow resistance. Even pore distribution prevents localized bypass channels that reduce filtration effectiveness. This helps maintain melt cleanliness even when impurity levels fluctuate. Users benefit from lower defect rates and more repeatable casting quality.

4. Q4: How does the Silicon Carbide Ceramic Foam Filter improve melt cleanliness during extended tapping cycles?
   During long taps, slag and oxide fluctuations increase, but the filter’s high porosity of 80–90% allows deep interception of suspended impurities. Its resistance to clogging ensures continuous filtration across varying melt loads. This maintains a stable cleanliness level throughout the entire cycle. Foundries can therefore achieve lower scrap rates on long production runs.

5. Q5: How does the Silicon Carbide Ceramic Foam Filter help control surface finish variation in castings?
   By preventing oxide re‑entry and capturing micro‑impurities early, the filter reduces irregularities that affect surface finish uniformity. This leads to more predictable machining behavior, especially on components that require smooth functional surfaces. It also helps decrease the number of parts needing post‑processing corrections. The result is a more stable finishing workload across batches.
