Vertical vacuum sintering furnace is a furnace that uses induction heating to sintering the heated items protectively. 

It can be divided into power frequency, medium frequency, high frequency and other types, 

which can be classified as the subclasses of vacuum sintering furnace. Vacuum induction sintering furnace is a complete set of equipment 

for sintering carbide cutter head and various metal powder pressors by using the principle of medium frequency induction heating under vacuum 

or protective atmosphere conditions. It is designed for the industrial production of hard alloy, metal dysprosium and ceramic materials.

The function of vertical vacuum sintering furnace is to heat powder, powder billet or other forms of materials in vacuum environment at appropriate temperature, 

with the help of atomic migration to achieve the connection between particles. The purpose of sintering is to make the porous powder pressed blank have a certain structure and properties of the alloy.

Main principle and application of vacuum sintering furnace:

Vacuum sintering furnace is in the vacuum after hydrogen filling protection state, using the principle of medium frequency induction heating, 

so that the tungsten crucible in the coil to produce high temperature, through the heat radiation conduction to the work, 

suitable for scientific research, military units to refractory alloy such as tungsten, molybdenum and alloy powder forming sintering.

Main structure and composition of vacuum sintering furnace:

Structure form for vertical, under the discharging way. Its main components are: electric furnace body, vacuum system, 

water cooling system, pneumatic system, hydraulic system, inlet and outlet mechanism, base, table, induction heating device 

(tungsten heating body and advanced insulation materials), inlet device, intermediate frequency power supply and electrical control system.

Main functions of vacuum sintering furnace:

After vacuuming, hydrogen gas is filled to control the sintering state of the pressure and atmosphere in the furnace. 

Available optical fiber infrared radiation thermometer and armored thermocouple continuous temperature measurement (0 ~ 2500℃),

 and through the intelligent temperature control instrument and set program compared, 

select the implementation of the state feedback to the medium frequency power supply, 

automatic control of the temperature and insulation program.
