- Brother Furnace
MoSi2 heating elements, unlike SiC ones, are individually replaceable. Extending their life reduces costs significantly.
Key Factors
- Environment: Alternating between reducing and oxidizing environments shortens lifespan.
- Temperature: Brother Furnace's 1700-type elements last longer at 1600°C than at 1700°C. For 1700°C, use 1800-type elements.
- Failure mechanism: Gradual thinning due to oxidation and grain growth.
Key Factors
- Use only in air or inert gases. Avoid active gases like H2, Cl2, and SO2.
- Minimize exposure to 400-700°C range.
- Handle carefully due to brittleness. Limit heating/cooling rate to 10°C/min.
- Check connections quarterly.
Lifespan extension tips
- MoSi2 heating element is only suitable for use in air or inert gas environments. Other active gas, such as H2, Cl2, and SO2, will damage the heating element.
- Please don’t use the furnace at 400 – 700℃ temperature range for a long time because the MoSi2 heating element will be easy to be oxidized in the temperature range.
- MoSi2 heating element is very brittle. Please pay great attention during moving and handling. Also, please avoid rapid heating and cooling to avoid the heating element broken. Max. 10℃/min heating or cooling rate is suggested.
- Please check the heating element every 3 months to see if they are in good connecting condition. If the connection gets loose, please open the over and tighten it properly.
By following these guidelines, you can maximize MoSi2 heating element performance and longevity, reducing operational costs and improving efficiency.
