Vacuum Gas Quenching Furnace for quenching high-speed tool steel, measuring vacuum hardening and cutting steel, tool steel, and other alloy steel.
Brother vacuum gas quenching furnace is made up of a furnace shell, molybdenum/graphite heating chamber, vacuum system, and cooling system. The heating chamber material is graphite felt. The furnace includes the Vertical type and Horizontal type, and blowing methods 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, and can be used for heating treatment of annealing, tempering, quenching, brazing, etc.

Vacuum gas quenching furnace features
- The heating chamber is composed of a molybdenum/graphite heater, molybdenum foil/graphite soft 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, 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 1200℃ to 300℃ less than 5min.
