Typical Applications
Laboratory Atmosphere and Muffle Furnace Chambers
Custom‑shaped chambers for muffle furnaces and atmosphere‑controlled laboratory furnaces. Chambers can be machined as one‑piece or segmented designs to accommodate different heating element configurations and temperature requirements. Precise dimensional control ensures minimal clearance gaps and optimal thermal efficiency.
Vacuum Furnace Hot Zone Liners
High‑purity ceramic fiber chambers for vacuum furnace hot zones. Low outgassing characteristics prevent contamination of processed materials. Suitable for both graphite and metal hot zone configurations with temperature ratings up to 1900°C.
Tube Furnace Split Chambers
Clam‑shell and split‑type chambers for tube furnaces. Designed for easy access to work tubes and heating elements. Available in multiple temperature grades with precision‑machined mating surfaces for uniform heat distribution along the tube axis.
R&D and Pilot Plant Reactor Liners
Custom‑engineered chambers for pilot‑scale reactors and R&D test equipment. Complex geometries with integrated ports, viewing windows, and thermocouple penetrations can be machined directly from customer drawings.
Retrofit and Replacement Chambers
Replacement chambers for aging or damaged furnace linings. Existing furnace dimensions can be measured and replicated to restore original performance or improve thermal efficiency.
Selection Guide: Which Thickness Should I Choose?
| Continuous Operating Temperature | Recommended Classification Grade | Recommended Thickness | Notes |
|---|---|---|---|
| ≤ 1250°C | 1400°C | 25 – 50 mm | Standard insulation thickness |
| 1250°C – 1450°C | 1600°C | 50 – 75 mm | Increased thickness for energy efficiency |
| 1450°C – 1650°C | 1700°C – 1800°C | 75 – 100 mm | Thick-walled design for demanding conditions |
| > 1650°C | 1900°C | 100 – 150 mm | Consult technical team for specific requirements |
Selection Notes:
- Chamber wall thickness affects thermal efficiency, heat-up time, and mechanical strength.
- Classification temperature ≠ continuous use temperature — the recommended continuous use temperature is approximately 150°C – 200°C lower than the classification temperature.
- Select the most appropriate grade and thickness based on actual operating temperature and furnace design — neither over-specify and waste budget, nor under-specify and shorten service life.
- For vacuum or specialty atmosphere applications, additional purification treatments may be recommended. Please consult our technical team for specific requirements.
