Elevator hearth furnaces

Gas tight elevator hearth furnace

  • Elevator hearth furnace for debonding and sintering
  • The workpieces are contained within an inconel 601 bell type retort, with a maximum load of 100kg
  • A Laminar flow of clean air across the product is provided
  • Raising and lowering of the hearth is by an elevator platform
  • Gas tight retort dimensions: 500mm high x 475mm maximum diameter
  • Maximum temperature 1100°C, working temperature 1000°C
  • Element type: resistance wire spiral supported in grooved ceramic side panels, arranged in a hexangonal formation to surround the retort and reduce distortion and ensure even heating and long life
  • Insulation: low thermal mass insulation combined with nickel chromium tungsten iron alloy hearth plate to support the load
  • 415-240 volts or 380-220 volts three phase and neutral, 44kW

High temperature elevator hearth furnace

  • Electrically operated elevator hearth ensures smooth loading and unloading of work piece
  • Chamber dimensions: 250mm high x 200mm maximum diameter, (actually an hexagonal shape chamber)
  • Maximum temperature: 1700°C; maximum continuous operating temperature 1650°C
  • Heat up time: approximately 80 minutes to 1600°C
  • Element type: molybdenum discillicide heating elements arranged vertically around chamber walls
  • Insulation: refractory brick hot face backed by ultra-high purity alumina low thermal mass insulation for rapid response rates and maximum thermal efficiency and stabilty
  • Dual display PID temperature controller/programmer with 8 segment pairs (type Eurotherm 3216P1) plus independent overtemperature controller (type Eurotherm 2116) to protect from overheating
  • Type B thermocouple with 0.5mm diameter wire
  • 415-240 volts three phase with neutral, 9kW
