Front Loading / Horizontal Vacuum Furnace by Therelek

Therelek’s Horizontal Vacuum Furnace is known to have a sturdy cold wall as a structure with a metallic or graphite hot zone. Having sliding doors, the material is loaded from the front of the horizontal heat furnace that in an overall manner, ensures excellent uniformity throughout the chamber.

Rapid cooling of high-pressure gas is carried out in a horizontal vacuum furnace, which is required for various other engineering processes. These furnaces have excellent process parameters and can support various job loads and sizes. Complete automation is possible for vacuum and heating cycles.
  • A bulk of high technology engineering industries like aerospace, auto, defence, atomic, etc. carry out their vacuum heat treatment in the Horizontal Gas Quench vacuum furnace.
  • In the vacuum heat treatment involved in the horizontal furnace, includes processes like Harding, tempering, annealing, solution ageing, stress-relieving, sintering, Brazing etc.
  • Being computer operated, the horizontal vacuum furnaces are fully automated with recipe-driven and also known for unique customizations for multilevel operation authorizations.
  • The complete cycle of the vacuum furnace operation is carried out starting from recipe selection, evacuation control, heating soaking and quenching cycles, control by SCADA, temperature programming controller, power thyristor, instruments and thermocouple, etc; in order to get the same results in repeated batches.
  • Vacuum furnace systems designed for full AMS2750E and CQI-9 compliance.
  • The vacuum furnace hot zone is of all metal, all Graphite and also a combination of graphite and metal.
  • The vacuum furnace is designed and programmed as per recipes for various modes of heating like vacuum heating, inert gas heating, partial pressure heating, convectional heating.
  • Customized vacuum furnace for internal or external rapid cooling systems to achieve uniform components involves cooling modes like fast cooling, vacuum cooling, static inert gas cooling, controlled cooling with inbuilt closed-loop operating blower, heat exchanger and 360 deg gas nozzles/controller opening flaps.
  • There is hardly any distortion of the components by vacuum heat treatment.
  • All components are also readily accessible for easy maintenance and repair. The vacuum furnace is also designed with no moving parts in the hot zones to minimize maintenance and downtime.
  • The vacuum furnace body/casing designed as per the ASME Code Section VIII Division 1 & 2.
  • The casing of the vacuum furnace is fabricated and tested as per ASME code Section IX.
  • The vacuum furnace front door is fitted with Hydraulic Operated Lockring (autoclave type).
  • Save up valuable floor space with an internal quench design which in return gives a compact furnace layout.
