What is the principle of a vacuum sintering furnace?

Vacuum sintering furnace

The vacuum sintering furnace is a furnace with protective sintering of the heated articles in the vacuum environment, which has a lot of heating methods, such as resistance heating, induction heating, microwave heating and so on. Vacuum induction furnace is a furnace with protective sintering of heated articles by induction heating. It can be divided into industrial frequency, medium frequency and high frequency type. It can be attributed to the subclass of vacuum sintering furnace. Vacuum induction sintering furnace vacuum induction sintering furnace is designed for the industrial production of hard alloy, dysprosium metal and ceramic material by using the principle of medium frequency induction heating to make the hard alloy cutter head and various metal powder compacts as a complete set of equipment under the vacuum or protective atmosphere. kejia vacuum induction tungsten sintered hydrogen furnace
one, the main principle and use of vacuum induction tungsten sintering furnace is under the condition of hydrogen protection after vacuum pumping, using the principle of medium frequency induction heating, making the tungsten crucible inside the coil high temperature, through the heat radiation conduction to work, the application of Yu Keyan and military unit to refractory alloy. Such as tungsten, molybdenum and their alloys are sintered and sintered.
Two, the main structure and composition structure form is vertical and lower discharging way. The main components are: electric furnace body, vacuum system, water cooling system, pneumatic system, hydraulic system, import and export mechanism, base, worktable, induction heating device (tungsten heating body and advanced insulation material), power supply device, medium frequency power supply and electrical control system.
Three, the main function is to fill hydrogen protection gas after vacuuming, and control the sintering state of pressure and atmosphere in the furnace. The optical fiber infrared radiation thermometer and the armoured thermocouple can be used to measure the temperature (0~2500 degrees C) continuously. After comparing the intelligent thermometer with the setting program, the state feedback is fed to the medium frequency power supply, and the temperature is controlled automatically and the thermal insulation program is automatically controlled.
