Key Features
- Extended Service LifeCombination of silicon carbide's hardness and graphite's lubricity resists wear, erosion, and thermal fatigue, outperforming traditional graphite or clay-bonded crucibles.
- Energy EfficiencyHigh thermal conductivity reduces melting time and energy consumption, lowering operational costs and environmental impact.
- Optimized Melt QualityNon-reactive nature prevents contamination of molten zinc, ensuring high-purity outputs for precision applications like Zamak alloy production.
- Versatility and ReliabilitySuitable for both batch and continuous melting processes, performing consistently in high-temperature environments (zinc melting point: ~420°C).
- Cost-EffectivenessHigher initial investment than standard graphite crucibles, but extended lifespan and reduced downtime result in lower total cost of ownership.
