Product Description

Product Description

CE Certified High Temperature Vacuum Hardening Kiln for Aerospace Parts

Brother Furnace gives you: Excellent Uniformity, Accurate Control, and Perfect Vacuum Condition!

Vacuum Gas Quenching Furnace for quenching high-speed tool steel, measuring vacuum hardening and cutting steel, tool steel, and other alloy steel.

Vacuum gas quenching furnace features

• The heating chamber is composed of a molybdenum/graphite heater, molybdenum foil/graphite soft felt,  the max temperature is 1320ºC.
   
• 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, a hearth, and an Al2O3 sticker. This structure will prevent the adhesion between the platform and the 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 1-10 bar.
  Max cooling rate: from 1200ºC to 300ºC less than 5min.
