Application Notes

Attention 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, toxic or explosive gasses are not recommended for use with this furnace without necessary safety controls and supervision.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.
  • Performance degradation (i.e. furnace can not reach the maximum temperature of 1500°C or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen. Please order the replacements from the standard package list in below.
