Vertical Bottom Loading Vacuum Gas Quenching Furnace

Vertical Bottom Loading Vacuum Gas Quenching Furnace
Product Description

Description

Vertical bottom loading gas quenching furnace is used for vertical gas quenching of materials of tool steel, die steel, high speed steel, super high strength steel, etc. It is specially applied for vacuum gas quenching of large size easy deforming products like long rod type parts, axle parts, plate type parts, etc. The components feature little deformation and good effect.

Technical Features

  • The vacuum gas quench furnace is vertical, single chamber, bottom loading structure. It is an optional to choose the moving-out bottom door device according to customers requirement.
  • Excellent temperature uniformity realized by octagon-shaped furnace hearth.
  • Bottom door device structure is optional for ball bearing screw or trapezium screw, nut moving or screw moving.
  • The elevation device frame is equipped with auto-balance correction device to eliminate the accumulated error. The elevation is stable and without vibration.
  • For different cooling speed requirements, it can use single heat exchanger furnace hearth or dual, multi-stage heat exchanger furnace hearth.
  • Variable direction cooling technology, cooling it can do both vertical injection cooling and 360° all around. 


Optional Configuration of Vertical Bottom Loading Gas Quenching Furnace

  • Bottom loading: the bottom door can move and be fixed horizontally
  • Vertical movement: screw moving/nut moving
  • Gas quenching type: 360° nozzle gas inject cooling/external heat exchanger cooling
  • Furnace hearth: Graphite heating elements and graphite felt heat insulation/Moly heating element and metal heat insulation
  • Vacuum pump and gauge: Foreign brand/high-quality Chinese brand
  • Vacuum degree: High vacuum/medium/vacuum
  • PLC: OMRON/Siemens/Mitsubishi
  • Temperature controller: SHIMADEN/EUROTHERM/Honeywell
  • Thermocouple: S type, K type, N type
  • Recorder: Paperless recorder/paper recorder
  • HMI: Simulation screen/Touch screen
  • Electric components: High-quality domestic brand/Schneider/Siemens
