Most electric resistance furnaces fitted
heating coils or superkanthal heating elements can be supplied in vacuum
implementation.
The ovens are equipped with a high-strength stainless steel vacuum outer container,
rotary vacuum pump, equipment for supply and discharge of technical gases,
explosion flap, or a device for burning gases. Can also be added
equipment for mixing different gases in precisely defined concentrations.
Furnaces can be chambered, cylindrical or elevator.
The maximum temperatures depend on the degree of vacuum and when using technical gases
reduce to temperatures recommended by the manufacturer of heating resistance materials.
As an example and reference, a vacuum furnace in an elevator design can be mentioned
enabling observation, analysis and modeling of melting processes at
glass processing. The melt sample is captured by a video camera from the left side
against the black background on the right.The inner space of the furnace is
designed for temperatures up to 1600°C and for the possibility of various applications
gaseous atmospheres.
The furnace was developed in cooperation with VŠCHT Prague.
Furthermore, for example, a vacuum furnace was successfully developed and tested in operation
hydrogen atmosphere with a temperature of 1550°C for metal sintering.
The production of vacuum furnaces, their dimensions, parameters and design are governed by the customer's requirements.
