1700°C Vacuum Chamber Atmosphere Furnace for Silicon Carbide Heating Elements 

Vacuum chamber atmosphere furnace for silicon carbide heating elements, USES the three layers of shell structure and the Japanese island of 40 program temperature control system, electric phase-shifting trigger, thyristor control, furnace using polycrystal line alumina fiber materials imported from Japan, equipped with air cooling system between internal and external bile, can rapid cooling.

Using shell overall sealing cover board and the oven door seal adopts high temperature silicone o-rings, oven door is equipped with water cooling system, gas after flowmeter by the breech, after furnace, gas outlet valve discharge by the door of the oven.

The furnace can be sintered in a vacuum. The furnace has a quick connector with KF25 on the side, which can be connected with vacuum pumps. The vacuum pump has a smoke filter and a suction nozzle with a dust filter.

With corrugated pipe, vacuum pump (connected to the furnace and vacuum tube), KF25 quick card sets, vacuum flapper valve, resistance vacuum gauge, etc., whereas the minimum vacuum degree is less than 5 pa, can also be hydrogen and argon, nitrogen, oxygen, carbon monoxide, protective gas such as ammonia decomposition gas, &energy-saving small size, low temperature field balancing, surface temperature and elevating temperature rate, energy saving, universities, research institutes, industrial and mining enterprises do protect the sintering atmosphere, reducing atmosphere with the ideal product.

The sealing of the furnace is made of glove box technology. The sealing effect is very good. It can be used in a vacuum or atmosphere, and it can ensure that the pressure gauge is not deflected within 5 hours.


1. Heating element


(1) the hot end roughness d of the silicon carbon rod is 14mm, the average factory adopts 12MM, the heating end is thick, the surface load of the rod is low, and the service life is long.

(2) the length of the cold end of m is 210mm. The average manufacturer adopts 180mm, and the cold end has a low temperature.

(3) the surface oxidation of the silicon carbide rod is compact and can better protect the carbon rod.


2. Install air switches and leakage protectors:

When an electric current or leakage, an empty meeting automatically disconnects.

3. Can connect with computer (Optional)

Furnace with communication interface and software, can be directly through the furnace computer control of each parameter, and can be observed from the computer PV on the stove and SV temperature and the running situation, the actual temperature of the furnace curve drawing computer real time, and can keep the temperature data of each time, can call up at any time

4. Chamber


Imported            VS                               Chinese


1. High quality high pure alumina polycrystalline fiber cured furnace with vacuum suction and filter molding. 

2. Adopt Japanese technology to form.

3. Low heat capacity and low heat conduction coefficient of furnace materials, resulting in less heat dissipation, good insulation and high reflectivity. Temperature equilibrium.

4. Long, high temperature and high resistance to heat and shrinkage of alumina filament.

5. The surface of the furnace is smooth and easy to remove powder.

6. Optional UL certified electrical board (all imported electrical appliances approved by UL)
