Application
1600C Vacuum Atmosphere box furnace mainly provides a high-temperature heat treatment environment for industrial, research institutes, factories and other industrial laboratories, and is applied to new materials such as metal materials, graphite materials, lithium battery materials, crystalline materials and so on.
Application Notes
• For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 5 °C/min.
• The cooling rate shall also not exceed 5 °C/min.
• 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.
• The refractory block must be inserted before closing the door.
