The furnace is made of polycrystalline mullite fiber/high quality new technology nano ceramic foam fiber materials, high cleanliness, corrosion resistance, using high quality silicon molybdenum rod as the heating element, heating cavity on all sides, uniform temperature field, electric lifting mechanism, stable base. The equipment is easy to operate, stable temperature control, good temperature uniformity, high efficiency and energy saving, etc., suitable for universities, scientific research institutes experiment and enterprise batch production.

Reasonable structure:

(1600 type bell jar furnace) The furnace is made of high quality mullite ceramic fiber materials, which can be used below 1600℃.

(Model 1750 bell jar furnace) The furnace is made of high quality new technology nano ceramic foam fiber material splicing, life is 2~3 times of fiber material, high cleanliness, corrosion resistance, high temperature resistance can be used for a long time below 1700℃. The low expansion and shrinkage coefficient of the material can eliminate the deformation and collapse of the furnace.

Uniform temperature field: silicon and molybdenum rods are uniformly arranged on all sides of the furnace to improve the uniformity of temperature field. Heating element is installed independently, easy to detect and replace, do not stop work to change rod can reduce the loss in production and experiment.

Easy to operate: Standard operating system for manual program control system. It can also be upgraded to a touch screen integrated control system to facilitate the use of long-term repetitive work. The exhaust device of the system can be opened and closed automatically according to the program, and can also be switched manually.

Lifting stability: electric lifting platform combined with cart type design, that is, to achieve stable lifting and to achieve the end of sintering after the fast take and release of materials. In the cooling stage, the lowering position of the burner door can be set according to the user's requirements to speed up the cooling.

Use safety: the lifting mechanism end using travel switch, to ensure the reliability of equipment operation; Furnace column guide design, avoid the occurrence of chain drive chain teeth jump teeth jitter, hydraulic drive loopholes; At the same time, the electric furnace also has the function of opening the door and power off and over temperature protection.
