Furnace Description

The heat treatment plant is used for a hardening process consisting of a continuous hardening furnace with special articulated chain, a subsequently added hardening chain system as well as a pusher type articulated chain tempering furnace with cooling tracks at the inlet and at the outlet.

The Ruhstrat Heat Treatment Plant consists mainly of the following elements:

  • Continuous furnace run by protective gas with special articulated chain as hardening furnace with electrical steel tube heating
  • Automatic removal from furnace and loading of hardening chains
  • Double hardening chain system seated on a rotary table. The chain system is for cooling in the context of the hardening process.
  • Automatic removal of hardening chains and loading of tempering furnace
  • Pusher type articulated chain furnace with cooled infeed track and with electrical heating and air circulation
  • Cooling zone for cooling down of tempered semi-finished parts.
  • Switch cabinet area for control and process visualization of the complete plant
  • Gas steel tube burner and electrical heating can be combined for optimal temperature control
  • With car body parts produced by Ruhstrat roller hearth furnaces drivers all over the world drive more safely.
