Our charge operated hood furnace plants, e.g. for quenching and tempering of roller bearing rings up to a diameter of 1200 mm consist normally of the components: hood annealing furnace with muffle, salt quenching bath, cooling station, washing machine with salt recycling, chamber tempering furnace and charging barrow.

On special transport gratings the heat treatment material is transported by the rail guided charging barrow from station to station in automatic mode. Charges at a weight of up to
1200 kg can be heat treated. The salt quenching bath with air cooling or water cooling is designed for both bainitic as also for martensitic hardening.

Depending on the required throughput performance, as well as on the parts geometry and the possible feeding and output of parts we will design the plant or give you a recommendation for the optimum plant design.

Possible heat treatments processing:

  • Annealing
  • Tempering
  • Hardening
  • Quenching and tempering
  • Carburization
