Product Details

Fast Cooling Vacuum Gas Quench Furnace, Vacuum Quench Furnace up to 1320°C

The vacuum gas quenching furnace is mainly used in vacuum bright quenching and sintering, brazing of tool steel, die steel, elastic alloy, stainless steel, 3D additional material, etc. The furnace is mainly composed of a pressure tank, heating room, vacuum system, electric control system, air inflation system, water cooling system, pneumatic system, and carrier cart, etc.

The heating chamber is composed of graphite heater, graphite soft felt and hard felt, the max temperature is 1320℃.
The multiserial graphite spray nozzle located inside the heating chamber along with the induction inwall. The gas uniform 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 temperature.
Gas cooling system: which is composed of 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 1-6 bar.
Max cooling rate: from 1200℃ to 300℃ less than 5min. (The cooling water temperature is lower than 35℃)
