4.5L Portable PID Control Box Type Muffle Furnace 1800C Lab Using
High Temperature Oven
Description of 1800C box type muffle furnace:
Box type muffle furnace is adopted high quality resistance wire as
heating element with dual shell structure and intelligent
auto-control temperature system, SCR control, phase shifting
trigger. The furnace chamber is adopted the 1800 type
polycrystalline alumina fiber. Equipped with intelligent cooling
system between the dual shell, when the surface temperature reach
to 50℃, the cooling fun will be start working automatically, so it
can ensure the surface temperature is low; Using constant current
soft-start control, to extend the life of heating elements.
Main usage of box type muffle furnace:
1. In chemical analysis
2. Physical decomposition and synthesis ,superhard materials (such
as ceramic)
3. Metal heat treatment of sintering process research and other
scientific experiments
4. Universities and colleges ,scientific research institutes
5. Rare and precious metal smelting and purification
