Ⅱ . Application Notes

Using Attentions

●  Cooling rate shall also not exceed 10℃ /min.   

●  Toxic or explosive gases 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.

●  Refractory door block must be inserted before closing door.
