Atmosphere Control Quenching Furnace


Atmosphere Control Quenching Furnace


This furnace operation of firing cycles where atmosphere condition can be altered during operation cycle, from oxidizing, (such as air to inert atmosphere), or argon/nitrogen to rough vacuum.
This type of furnace makes multi-atmosphere process in one cycle possible: binder burn out in air and parts sintering under vacuum or inert gas atmosphere.
It is designed for accurate air/inert gas flow rate control, accurate temperature control, excellent temperature uniformity, long lasting performance and safe operations.
It is ideal for laboratories and small scale production for temperatures up to 1600 ℃.


This type of furnace is widely used for heating treatment of materials in vacuum, recursive, protective atmosphere, also can be used for heating treatment of special materials. The furnace chamber is ceramic fiber with excellent thermal insulation.


1: Top quality heating elements doesn't pollute the heating sample.
2: Better temperature uniformity and better thermal insulation.
3. Power control with 51 segments programmable.
4. B type high accuracy thermocouple.
5. Vacuum system and gas flow control system.
6. High purity alumina ceramic fiber chamber.
