Inert Atmosphere Controlled Furnace For Chemical Material Research

Atmosphere Furnace.jpgAtmosphere Furnace.jpg

1.Main application:Ceramics, metallurgy, electronics, glass, chemical, machinery, refractory materials, special materials, building materials, universities, research institutes, industrial and mining enterprises to do powder roasting, ceramic sintering, high temperature experiments, material processing, quality universities, research institutes, Industrial and mining enterprises do high temperature atmosphere sintering, atmosphere reduction, cvd experiment, vacuum annealing, etc.


1. The furnace uses high quality resistor wire as heating element, adopts double shell structure and 31 stage program temperature control system, phase shift trigger, silicon controlled control, high quality high purity alumina fiber, vacuum forming fiber light plate material. Double furnace structure is adopted. The furnace has the advantages of equilibrium of temperature field, low surface temperature, fast temperature rising and lowering rate, energy saving and so on.


3.A new type of high performance high energy saving ceramic fiber material with high performance and energy saving is developed by using the advanced international technology. The external temperature can be reduced to normal temperature and the temperature distribution of the inner cavity can be uniform by adopting the double layer structure of the ceramic fiber material of the energy saving type.

Control characteristics

The modular structure of the control system, the long life design of the key components of the equipment, the process is simple and reliable, the stability is good, and the precision is high.





Air cooling system

The fan impeller is mounted directly on the bottom of the double furnace shell and assembled with the control system. When the sintering furnace is heated, air cooling can reduce the surface temperature of the furnace shell and protect the heat of the electric appliance, and the personnel operation is safer and the efficiency is improved.






The lining is made of high-quality pure alumina fiber, vacuum-formed fiber-reinforced light-weight board material, light-weight hollow-balloon alumina board, high temperature, low heat storage, rapid heat and cold resistance, no cracks, no slag, good heat preservation performance (energy saving) The effect is more than 80% of the old electric furnace). The double-furnace structure patent is a patented feature that not only heats up quickly, but also has durability and long-term use without collapse.



 Heat insulating material


High-quality alumina multi-fiber insulation material, insulation layer is 150mm.


The furnace shell is welded by steel plate and profile, and the outer casing is equipped with a removable protective plate. The protective plate is electrostatically sprayed and painted. Fine workmanship and beautiful appearance.


         Furnace structure

Double-layer furnace shell structure, air-cooled circulation, reducing the temperature of the shell. Shell surface temperature < 60 degrees

The surface of the inner furnace is coated with a high-temperature alumina coating to increase the heating efficiency of the equipment and to extend the life of the instrument.

Energy saving performance

Light weight, fast heating, energy saving more than 50%, save time and labor.
