V series Vacuum Furnace (Graphite)

Good Design Optimization / Temperature Uniformity / Fast Heating Speed / High Pressure Accuracy / Good Safety Performance

This vacuum furnace is a vacuum resistance furnace that uses graphite as a heating element, mainly used in ceramics, hard alloys.  Composite materials can also be used for heat treatment such as high-temperature sintering or annealing in vacuum or protective atmosphere, as well as for metal materials. High temperature heat treatment of materials under high vacuum conditions or degassing treatment of precious metal materials.

Technical Data

Adopting a horizontal and side door structure:

Loading and unloading materials, easy to operate;

Fast heating: Heating rate of 10°C/minute (≤ 1600°C), heating rate of 5°C/minute (>1600°C); 

Good design optimization: The heating chamber's thermal field has been simulated and calculated under thermal conditions, with very high temperature uniformity and compatibility. The heating elements and insulation layer are designed with modular optimization;

Adopting multi temperature zone control: Reserving multiple temperature measurement holes for high-temperature monitoring purposes;

Good temperature uniformity: The average temperature uniformity is ±5°C  (5-point temperature measurement, constant temperature zone 1000°C insulation for 1 hour before detection);

Fast cooling speed: Optional with a fast cooling system under a gas pressure of 2 bar to 10 bar, ensuring fast cooling and efficient operation of the workpiece after hot pressing;

Good stability: The equipment runs stably for a long time and has a very low failure rate;

Good safety performance: Adopting HMI+PLC+PID pressure sensing control, safe and reliable;

Strong scalability: Capable of sintering, annealing, degreasing, degassing, etc.

This equipment is a cycle operation type and can be used for graphite electrodes, ceramics, etc. under high temperature and high vacuum conditions, Sintering treatment can also be carried out under the condition of filling a protective atmosphere, or carbon fiber felt can be subjected to atmosphere treatment. Protection purification treatment and sintering process have been widely used in many industrial industries such as alloy and metallurgical industries. Applications such as hard alloys, refractory materials, powder metallurgy, and ultra-high temperature material firing all require application sintering process.

Such as carbon/carbon brake discs, carbon plates, hot pressing molds, high-temperature heating elements/fasteners, thermal field materials, Graphite products, carbon paper, carbon cloth, graphene, carbon nanotubes, thermal conductive films, etc.
