  • 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℃)
