Max 2400℃ High Temperature Vacuum Furnace With Thermocouple And
Pyrometer For Temperature Measuring
Products Characteristic
1. Horizontal design for easy loading/unloading and easy
maintenance.
2. Automatic control of the entire process
3. This kind of High Temperature Vacuum Furnace is single
room,horizontal type,recycle heating furnace, it adopt Molybdenum
heating element of low voltage and large current.All the technical
process is automatic controlled, monitored, chased, fault diagnosed
which showed and recorded by computer.
4. Furnace heating element, insulation and charging box are all in
cylindrical structure, compared with the traditional square
structure: Charging room is larger, size is more flexible, the
temperature and atmosphere more uniform.
Applications: For Non-metal ceramic/SiC/Si3N4
Power supply: General standard is three phase five wire system AC380V±10% 50HZ.
Control power supply: Single-phase AC210V-250V 50HZ
design(Different countries and regions can be designed according to
local grid standards)

The furnace has three controlled heating zones and the following
main components:
1 Three duplex retractable thermocouples (TC) to control
temperature up to 1600°C; above this limit the TCs are retracted
out of the hot zone. Each TC has a protective tube.
2 Three infrared pyrometers (pyro), to monitor the temperature by
optical radiation of the bottom of the graphite tube of the pyro in
the range of 1600…2400°C. Each pyro is equipped with an
inert gas flushing system to prevent fogging of the sight glass
during operation.
3 Copper power bus between transformer and current feedthrough of
the furnace(copper busbar+dry type cable).
4 Graphite box in the heating zone of the furnace with doors on
both ends; doors are controlled by automatic actuators (for door
opening/closing during dewaxing).
5 The graphite box is equipped with a differential pressure relief
valve to prevent damage
to the graphite box when there is a large pressure difference
between the box and the furnace
chamber.
