V series Vacuum Furnace (TungSten)
FeatureThis vacuum tungsten strip furnace is a vacuum resistance furnace that uses tungsten strips as heating elements, mainly used in ceramics. Ceramics, hard alloys, composite materials, etc. are sintered and annealed at high temperatures under vacuum or protective atmosphere, It can also be used for high-temperature heat treatment of metal materials under high vacuum conditions or for the removal of precious metal materials gas treatment.
Adopting a horizontal and side opening door structure: high loading and unloading accuracy, easy operation;
Fast heating: heating rate of 10°C/minute (˛ 1600°C); Heating rate of 5°C/minute (>1600°C);
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);
Good safety performance: Adopting HMI+PLC+PID pressure sensing control, safe and reliable;
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;
High degree of automation: multi parameter recording and monitoring, user-friendly human-machine interface, stable operation;
Fast cooling speed: optional with a fast cooling system under a gas pressure of 2bar-10bar to ensure hot pressing of the workpiece, Fast cooling after completion and effecient operation;
Strong scalability: capable of sintering, annealing, brazing, degassing, hydrogen gas, etc.
