Continuous Pusher Furnace
Controlled Carburizing at high throughput

Aichelin Unitherm continuous pusher furnaces are designed for applications that require a uniform material flow and precisely controlled carburizing. The multi-zone furnace concept enable accurate temperature and atmosphere control throughout the entire process. In combination with integrated quenching systems, and in particular with efficient and sustainable high-pressure gas quenching, stable series processes with reproducible component properties can be achieved.

Additional technical features

  • Loading in Carburising furnace via bottom loader. This eliminates requirement of gas curtain and lowers running cost.

  • Free Oil Quench Tank with two dedicated elevators for Quenching and Unloading from Quench Tank.

  • Two separate free Oil Quench Tanks option available.

  • Pre and post wash with FLEXICLEAN (Vacuum Washing Machine) option available.

  • Holding Chamber with Bottom Lifter with Servo Drive for high precision and accuracy for 6 - 8 layer per batch.

  • Press Quenching done by FANUC Robots.

  • Furnace with high-pressure gas quenching with N2 option available for lower distortion.

Questions & Answers
FAQ – Aichelin Unitherm continuous pusher furnace
The furnace is suitable for case hardening, through hardening, carbonitriding, normalising and annealing applications
The system supports oil quenching, salt quenching and press quenching options. High-pressure gas quenching with nitrogen is also available for low distortion applications.
Process reliability is ensured by precisely controlled furnace zones with defined gas circulation and continuous atmosphere control. Process monitoring and documentation are provided via the FOCOS 4.0 process control system.
High throughput is achieved through multi-line design, automatic batch handling, and optimized heat transfer in all process zones – making the system ideal for automated mass production.
Aichelin Unitherm continuous pusher-type gas carburizing furnace systems operate with high efficiency. Recuperative burner technology and durable insulation significantly reduce energy consumption.
The integration of FOCOS 4.0 enables centralized process monitoring, batch tracking, fault diagnostics, and complete data recording for quality assurance and energy analysis.
Aichelin Unitherm continuous pusher furnaces can be designed for all common tray sizes. The furnace configuration, quenching systems, automation level, atmosphere system and handling arrangements can all be customised according to application and production needs.
Yes, Aichelin pusher-type furnace systems can also be equipped with state-of-the-art electric heating elements. This supports customers in reducing energy consumption.
