The primary principle of vacuum brazing furnace

Vacuum brazing furnace is in a vacuum environment to maintenance of sintering furnace heated objects, the heating method is more, such as resistance heating, induction heating, microwave heating, etc. Vacuum induction furnace is the use of induction heating to maintenance of sintering furnace heated objects can be divided into the power frequency, medium frequency, high-frequency, such as type, can be attributable to a subclass of vacuum brazing furnace. Vacuum induction furnace Vacuum induction furnace is in a vacuum or maintain atmosphere conditions, using the principle of intermediate frequency induction heating make carbide cutter head, and all kinds of metal powder limit sintered body implementation of complete sets of equipment, is for hard alloy, metal dysprosium, and planning in the industrial production of ceramic materials.
A hydrogen sintering furnace, vacuum induction tungsten first principle and use vacuum induction furnace tungsten is after vacuum filling hydrogen maintenance conditions, using the principle of intermediate frequency induction heating, the high temperature of tungsten crucible in the winding, after thermal conduction to the work, suitable for scientific research, military units for hard metal such as tungsten, molybdenum and its alloy powder sintering molding. Second, primary layout and layout method for vertical, the discharging method. Its primary group became: electric furnace body, vacuum system, water cooling system, pneumatic system, hydraulic system and front-rear institutions, base, workbench, induction heating equipment (tungsten heater and high-grade thermal insulation material), into the electric equipment, intermediate frequency power supply and electrical control system, etc. Third, primary function After vacuum filling the hydrogen gas maintenance and control atmosphere in furnace pressure and sintering conditions. Available optical fiber infrared radiation thermometer and the armoured thermocouple temperature measurement (0 ~ 2500 ℃), and after comparing the intelligent temperature control and setting process, select performance status feedback to medium frequency power supply, automatic control temperature of concave and convex and heat preservation program
