Vacuum Oil Quenching Furnace

Vacuum oil quenching furnace

High Temperature Vacuum oil quenching furnace

The vacuum oil quenching furnace is mainly used in bright quenching and annealing of alloy steel, tool steel, die steel, high speed steel, bearing steel, spring steel, stainless steel. Also used in vacuum sintering of ceramic and hard alloy, metal material brazing, etc. The furnace is mainly composed by graphite chamber, graphite felt induction, PLC control system.

Vacuum oil quenching furnace features

  • Adopt the graphite tube as the heating element, with long lifetime and easy maintenance.
  • The compound flash-board has excellent heat insulation and trapping effect.
  • The structure is a double room, the back room is for heating, and the front room is for oil and gas cooling. The upside is a gas quenching room and the downside is oil quenching room, including lifting device, charging device, oil mixing device and oil heating device.
  • Lifting device: The lifting skip car is driving by screw and nut, and driving by a three-speed gear motor. There are three speed on lifting skip car, low speed for sending material, low speed start, high speed oil quenching and low speed location.
  • Oil mixing system: The mixer is driving by the reducer, the deflector could promote the circular flowing of vacuum quenching and promote the oil cooling capacity. The mixer is a standard part with low noise and high efficiency.
  • The workpiece transfer is smooth and flexible, safe, and reliable.
  • The gas cooling cover adopt staggered teeth flange structure to ensure the sealing in positive and negative pressure.
