Vacuum Gas Quenching Furnace

Feature:

• The heating chamber is composed by graphite heater, graphite soft felt and hard felt, the max operation temperature is 1300℃.
• 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 by graphite support, hearth and Al2O3 sticker. This structure will prevent the adhesion between platform and hearth during high temperature.
• Gas cooling system: which is composed by high press wheel blower, multistage high-efficient copper heat exchanger and duct deflector. Filling high purity N2 or Ar during gas cooling, spray to workpiece through duct deflector to achieve workpiece uniform cooling.
• The gas cooling pressure is adjustable from 1-10bar.
• Max cooling rate: from 1150℃ to 250℃ less than 7min. (The cooling water temperature is lower than 35℃)
