Principle of vertical vacuum sintering furnace

classify :Product knowledge

The furnace for protective sintering of heated items in a vacuum environment has many heating methods, such as resistance heating, induction heating, microwave heating and so on. Vacuum induction furnace is the use of induction heating to heat the goods for protective sintering furnace, can be divided into power frequency, medium frequency, high frequency and other types, can belong to the subclass of vacuum sintering furnace. Vacuum induction 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 a VSWF vacuum induction tungsten sintering hydrogen furnace designed for the industrial production of cemented carbide, metal prosium and ceramic materials.

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

Second, the main structure and composition. The structure form is mostly vertical, down discharging mode. Its main components are: electric furnace body, vacuum system, water cooling system, pneumatic system, hydraulic system, inlet and outlet mechanism, base, workbench, induction heating device (tungsten heating body and advanced insulation materials), power supply device, medium frequency power supply and electrical control system.

Three, the main function. After vacuuming, hydrogen protective gas is filled to control the sintering state of the pressure and atmosphere in the furnace. The optical fiber infrared radiation thermometer and armored thermocouple热电偶 can be used to continuously measure the temperature (0 ~ 2500℃), and after comparing the intelligent temperature control instrument with the setting program, the execution state is selected and fed back to the intermediate frequency power supply to automatically control the temperature and the heat preservation program.
