Principle and application of second hand vacuum sintering furnace

The second-hand vacuum sintering furnace refers to the furnace for protective sintering of heated articles in vacuum environment. There are many heating methods, such as resistance heating, induction heating, microwave heating, etc. Vacuum sintering furnace is a kind of furnace which uses induction heating to carry out protective sintering of heated objects. It can be divided into power frequency, medium frequency, high frequency and other types, which can be classified into the subclass of vacuum sintering furnace. Next, I will give you a brief introduction to the principle and use of second-hand vacuum sintering furnace.

Main principle and Application

The vacuum sintering furnace is to make the tungsten crucible in the coil produce high temperature by using the principle of medium frequency induction heating under the protection of filling hydrogen after vacuumizing. It is suitable for the powder forming sintering of refractory alloys such as tungsten, molybdenum and their alloys in scientific research and military units.

major function 

After vacuumizing, hydrogen protective gas is filled to control the sintering state of furnace pressure and atmosphere. Optical fiber infrared radiation thermometer and armored thermocouple can be used for continuous temperature measurement (0 ~ 2500 ℃), and the intelligent temperature control instrument (as shown in the figure below) is compared with the setting program, and the execution status is fed back to the intermediate frequency power supply to automatically control the temperature level and insulation program.

The second-hand vacuum sintering furnace is a complete set of equipment for sintering cemented carbide cutter head and various metal powder compacts under vacuum or protective atmosphere by using the principle of medium frequency induction heating. It is designed for the industrial production of cemented carbide, dysprosium metal and ceramic materials. The above is a brief introduction of the working principle and application of the second-hand vacuum sintering furnace. I hope it can help you.
