Vacuum Furnace with High Vacuum

Vacuum Carburizing

FineCarb® Vacuum Carburizing


  • Guarantee of carburizing repeatability and uniformity of the case from 0,1mm to 5mm.
  • Unique carburizing gas mixture.
  • Total elimination of process by-products, like soot and tar, green manufacturing process.
  • Automatic control of carburizing atmosphere flow, depending on charge size.
  • Reduction of cycle time by increasing the Carburizing temperature to 1150 °C.
  • Grains growth limitation in high-temperature Carburizing by PreNitLPC technology.

Gas Quenching

  • Easy control of cooling speed by software modificatíon of gas pressure and blower speed in appropriate cycle stage.
  • Suitable for various cooling gases including N2, He, or H2 with pressures up to 25 bar.
  • High capacity of quenching in Helium, close to quenching in oils
  • Separate cooling Chamber in double-chamber furnaces or modular systems increases the application for 16MnCr5/8620 steels (range MQ1/2 DIN 3990).
  • Uniform cooling and repeatable of distortion field,
  • lnnovative SECO/WARWICK circular cooling system allowing for fast cooling with use of reversible top/bottom gasf low.
  • The ConFlap convective heating system in single-chamber VPT furnaces allowing for hardeníng with shorter cycle times before Ms transformations significantly reducting part distortions.



SimVac Process Simulator

SimCarb module enables designing of vacuum carburizing processes prior to
running trials saving actual process time and reducing number of scrapped

  • Optimal segment planning of carburizing process splitto
    boost and diffusion (holding) phases.
  • Calculations based on steel grade, sizeand shape of parts,
    as well as Cooling profilefor hardening.
  • Manual or automatic simulation mode.
  • Carburizing cost reduction.
  • lntuitive users interface.
  • Fully compatible with furnace control system Secovac.

SimHard module – gas hardening simulator is an additional
technology support that enables:

  • Simulation of hardness distribution upon the basis of achieved carbon profile.
  • Including the cooling characteristics of SECO/WARWICK furnaces
    in to the calculations.
  • Designing of carburizing process for required mechanical properties TWV.
  • Detailed calculation of carbon profile considering charge configuration and
  • Manual or automatic simulation mode.

PreNitLPC® technology

  • Limitation of grain growth in
    high-temperature processes (above 1000°C).
  • Acceleration of case creation
  • Reduction of retain austenite and carbides
  • Shortening of process duration.
