Principle and application of vertical vacuum sintering furnace

Vertical vacuum sintering furnace is a furnace that uses induction heating to protect sintering of heated items, which can be divided into power frequency, medium frequency, high frequency and other types, and can be classified as a subclass of vacuum sintering furnace. Vacuum induction sintering furnace is a complete set of equipment for sintering cemented carbide cutter head and various metal powder pressing body by using the principle of medium frequency induction heating under the condition of vacuum or protective atmosphere. It is designed for industrial production of cemented carbide, prosium metal and ceramic materials.

The function of vertical vacuum sintering furnace is that powder, powder billet or other forms of materials are heated under vacuum environment at appropriate temperature, and the connection between particles is realized by means of atomic migration. The purpose of sintering is to make the porous powder compacted with a certain structure and properties of the alloy.

Main principle and application of vacuum sintering furnace:

Vacuum sintering furnace is in the vacuum after filling the hydrogen protection state, using the principle of medium frequency induction heating, tungsten crucible in the coil to produce high temperature, through heat radiation conduction to the work, suitable for scientific research, military units of refractory alloy such as tungsten, molybdenum and its alloy powder forming sintering.

Main structure and composition of vacuum sintering furnace:

The structure form is mostly vertical, under the discharging mode. Its main components are: electric furnace body, vacuum system, water cooling system, pneumatic system, hydraulic system, feeding and discharging mechanism, base, workbench, induction heating device (tungsten heater and advanced insulation materials), power intake device, intermediate frequency power supply and electrical control system, etc.

Main functions of vacuum sintering furnace:

After vacuuming, the protective hydrogen gas is filled to control the sintering state of the pressure and atmosphere in the furnace. The temperature can be measured continuously (0 ~ 2500℃) by using the optical fiber infrared radiation thermometer and the sheathing thermocouple. After comparing with the setting program by the intelligent temperature controller, the execution state can be selected and fed back to the IF power supply to automatically control the temperature and the heat preservation program.
