Application Notes

  • For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 10°C /min.
  • The cooling rate shall also not exceed 10 °C /min. 
  • This furnace lacks vacuum sealing, and it is not recommended to use toxic or explosive gasses in this furnace without necessary safety controls and supervision. 
  • Small cracks may appear on the surface of the refractory ceramics with overuse. This is a normal occurrence and the cracks may be repaired with alumina coating.
