application notes

for preserving the longevity of the furnace components,we recommend the heating rate not to exceed 10'C/oling rate shall also not exceed 10'C/min.this furnace lacks vacuum sealing.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 ceramic over extended use.this is a normal occurence and cracks may be repaired with alumina coating.refractory block must be inserted before closing door.
