Heat Treatment: Vacuum Furnaces

By Furnace Engineering

Furnace Engineering together with Ipsen offers a wide range of Vacuum Furnaces that cater for a huge variety of heat treatment processes including:

  • Bright hardening, annealing or tempering
  • Solution annealing
  • Degassing
  • Hard and high-temperature soldering
  • SolNit®
  • AvaC® (low-pressure carburising)
  • Plasma nitriding or carburising
  • Sintering

The furnace is designed for cost-effective operation. The low energy consumption and emission comply with the strictest environmental standards.

Key features:

  • Optimum hardness
  • Bright surface
  • Surface free from oxidation and decarburisation
  • Low distortion (for complex geometries)
  • Consistency & high quality
  • Reproducibility
  • Suitable for a wide variety of materials

Different types of horizontal, vertical, single or multi-chamber furnaces are available. They can be fitted with convection-type systems to increase throughput by reducing heat-up time and ensuring optimum temperature homogenity.

The Vacuum Furnaces can be fitted with the Ipsen convective heating system which will reduce heating time by 30% (for convective heat transfer up to 850°C) and shortening subsequent tempering cycles by up to 50%. Further, gas consumption is reduced as quenching gas is used as convective heat transfer medium during tempering.
