Pre-Vacuum Furnace (650℃) is mainly used in aerospace, aviation, aircraft manufacturing industry for precision parts with non-oxidation Tempering, protective atmosphere heat treatment.

Pre-Vacuum Furnace (200-650℃)

Application Range:

Pre-vacuum furnace (200-650℃) of ZRJ3 series is a high-energy and high-precision temperature controlled vacuum heat treatment furnace.

It’s mainly used in aerospace, aviation, aircraft manufacturing industry for precision parts with non-oxidation tempering, protective atmosphere heat treatment.

Structure description:

HKFurnace provides Vacuum Furnaces in custom designs and dimensions to match customer production and process requirements.

The pre-pumped vacuum furnace is mainly composed of pit type shell coiled with steel and furnace body made by welding section steel.

The furnace lining adopts the energy-saving composite fiber or full-fiber, which have remarkable effect on energy and power saving.The electric heating element use the high temperature resistance alloy element, which can last up to 5 years.

The furnace pot is made of imported high temperature stainless steel sheet.

The furnace cover is insulated with stainless steel and aluminum silicate fiber insulation module. the Vacuum seal stainless steel fan is installed to keep the air pressure stable and uniform temperature.

The cooling system can be equipped in the pre-vacuum furnace, and remove the heat nitrogen from the furnace and connect the cold nitrogen to the tank for the quick cooling circulation system.

Controller system:

The vacuum furnace panel is equipped with a vacuum interface, a protective atmosphere interface and a vacuum pressure gauge.

The Pre-vacuum furnace is divided into multi-zone temperature control, multiple microcomputer program control, automatically displaying the measured temperature, calculating the temperature ramp rate and the set value with overtemperature alarm and automatically process curve records.

The temperature control precision of which is 1 ºC.
