Product Description

Silicon Nitride Dewaxing Vacuum Sintering Furnace 

Many alternative dimensions and unlimited custom sulutions are available.

It is mainly used for dewaxing of silicon carbide ceramic materials (vacuum Ar carrier gas or hydrogen micro-positive pressure dewaxing), vacuum sintering, partial pressure sintering, pressure sintering, rapid cooling and other processes. It meets the strict requirements of furnace temperature uniformity and atmosphere uniformity in the sintering process of silicon carbide ceramic materials, and the furnace body structure design is advanced and reasonable, which is convenient for operation and maintenance. The main supporting components (control elements, sensors, graphite heating elements, thermocouples, main control valves, vacuum pumps, etc.) are at the international advanced level and can meet the requirements of long-term, stable and reliable mass production. At the same time, the equipment meets the national requirements for energy saving and environmental protection.

Model 339


Working temperature

1600℃(maximum working temperature)
1500℃(actual working temperature )


Pumping speed

The vacuum degree can reach 5Pa within 30min after the pump is started, and the limit vacuum value can reach 1Pa after pumping for 30min after reaching 5Pa

(After drying the furnace, under the empty furnace, clean and cold state.)


Leakage rate


(Measuring the limit vacuum after drying the furnace, stop the operation of the pump group and start the test. Average within 3 hours in empty furnace, clean and cold state)


Cooling speed


Empty furnace. The cooling time of cooling temperature from 800℃ down to 100℃ just cost less or equal 3 hours.(water temperature≤28℃, 2bar≤water pressure≤3bar)


Cooling speed

The inner furnace is equipped with rapid cooling fan and cooling water realize rapid cooling.
Heating rod material Graphite
Temperature control mode Three zone temperature control independently
Heating up speed


Empty furnace heating up≤5℃



Heating power


It is about 280KVA (the power configuration of the heating transformer is related to the heating speed, and the heating power can be automatically limited according to the actual use of the production).


UPS guarantee time


It can power the indicator lights and control the furnace when the power goes out,the time is more than or equal 80 minutes.
