Vacuum sintering furnace is in a vacuum environment to be heated objects in protective sintering furnace, its heating mode is more, such as resistance heating, induction heating, microwave heating, etc. Vacuum induction furnace is heated objects to make use of induction heating protective sintering furnace, can be divided into the power frequency, medium frequency, high-frequency, such as type, can be ascribed to a subclass of vacuum sintering furnace. Vacuum induction furnace is under vacuum or protective atmosphere conditions, using the principle of intermediate frequency induction heating make hard alloy tool bit and all kinds of metal powder compacting sintering of complete sets of equipment, is for hard alloy, metal dysprosium, designed in the industrial production of ceramic materials.
For more than a, main structure and the composition structure under vertical and discharging. Its main composition is: the furnace body, vacuum system, water cooling system, pneumatic system, hydraulic system and front-rear institutions, base, workbench, induction heating device (tungsten heater and advanced thermal insulation material), into the electric device, medium frequency power supply and electric control system, etc.
Second, the main function after vacuum filling the hydrogen gas protection, control of furnace pressure and state of sintering atmosphere. Available optical fiber infrared radiation thermometer and armoured thermocouple temperature measurement (0 ~ 2500 ℃), and through the intelligent temperature control after comparing with the setup program, select the execution state feedback to intermediate frequency power supply, automatic control temperature and heat preservation program.
Tungsten, main principle and USES vacuum induction furnace is after vacuum filling hydrogen protection condition, by using the principle of intermediate frequency induction heating, the high temperature of tungsten crucible in the winding, by heat conduction to work on, suitable for scientific research, military units for hard metal such as tungsten, molybdenum and its alloy powder sintering molding.
