High Temperature Vacuum Double Chamber Gas Quenching Oil Quenching Furnace Vacuum Carburizing Furnace

vacuum gas quenching furnace is made up of furnace shell, graphite heating chamber, vacuum system, and cooling system. The heating chamber material is graphite felt. The furnace includes Vertical type and Horizontal type, blowing method include circular blowing and up-down blowing. This furnace can be equipped with a hot stirring fan for low temperature stirring (Optional: Stirring fan) and can be vented at any temperature (Optional: valve heat exchanger).

This furnace is widely used in aerospace/aviation, weapons, automobiles, electronics, machinery industry, and other fields, can be used for heating treatment of annealing, tempering, quenching, brazing, etc.

The heating chamber is composed of a graphite heater, graphite soft felt, and hard felt, the max temperature is 1320℃.
The multiserial graphite spray nozzle is located inside the heating chamber along with the induction inwall. The gas uniform was sprayed from the spray nozzle during gas quenching.
The material platform is composed of graphite support, hearth, and Al2O3 sticker. This structure will prevent the adhesion between the platform and hearth during high temperatures.
Gas cooling system: which is composed of a high-press wheel blower, multistage high-efficient copper heat exchanger, and duct deflector. Filling high purity N2 or Ar during gas cooling, spray to the workpiece through duct deflector to achieve workpiece uniform cooling.
The gas cooling pressure is adjustable from 1-bar.
Max cooling rate: from 1200℃ to 300℃ less than 5min.

Application

Quenching of high speed steel, tool and die steel, stainless steel.

Solid solution treatment of stainless steel and titanium alloys.

Magnetic materials Vacuum heat treatment of magnetic materials.

High temperature brazing and vacuum sintering.

Performance features

Convection heating, to achieve rapid and uniform heating of low-temperature strands.

The heating chamber structure in the furnace provides more uniform heating, less power loss and energy saving.

Using a new type of carbon felt composite material, it is resistant to high temperature and high pressure airflow erosion, and the heat shield has a longer service life and is easier to maintain.

High-speed and high-pressure fans and high-efficiency copper-copper heat exchangers achieve rapid cooling.

Alternate cooling method achieves uniform cooling and ensures minimal deformation of the workpiece.

The cooling pressure and wind speed of the locomotive are adjustable to achieve graded cooling.

The vertical furnace adopts screw drive, which is flexible, safe and reliable.

Optional graphite or all-metal heating chamber.

Optional fully intelligent industrial computer control and a manual operating system are available, which are easy to learn, understand and operate.
