Description

Lenton Furnaces Elevator hearth furnace designed for applications such as High temperature annealing, Nitriding, hardening,  de-bonding and sintering of materials.

The work is contained within an inconel 601 bell type retort, with a maximum load of 100kg where a laminar flow of atmosphere gas is passed across the product.

The furnace is electrically heated with air / atmosphere circulation, 3 zone control, multi programme capability, atmosphere flow control, integrated top hat hoisting and with a built in rapid air quench facility. 

Raising and lowering of the hearth is by a linear actuated elevator platform.

Features

  • Usable gas tight retort dimensions: 500mm diameter x 500mm high
  • Maximum temperature 1100°C.
  • 2 stage gas atmosphere injection to the chamber currently set for Nitrogen and Nitrogen/Hydrogen mix with a separate Nitrogen gas seal for the hearth for nitriding.
  • Element type: resistance wire spiral supported in grooved ceramic side panels, arranged in a hexagonal formation to surround the retort and reduce distortion and ensure even heating and long life.
  • Balanced powered twin flues with controlled cool facility. 
  • Insulation: low thermal mass insulation combined with nickel chromium tungsten iron alloy hearth 
  • 415-240 volts or 380-220 volts three phase and neutral, 41kW heater power.
