Focus topic energy efficiency

Furnace specialists Otto Junker and its subsidiary Induga will be presenting their solutions in the induction melting and thermoprocessing equipment fields in Duesseldorf.

The focus topic of energy efficiency is also accompanied by further developments in plant availability and safety: A new learning module from the Otto Junker Academy will be presented that incorporates virtual reality. VR goggles can be used to simulate critical operating situations such as a ground fault message in a foundry environment. This allows both operating and maintenance personnel to be realistically trained for critical situations in an understandable and descriptive manner. The virtual environment enables tangible learning of correct behavior at the melting furnace.

Another advantage for optimized loss-free operating processes is demonstrated with IGBT converter technology (Insulated Gate Bipolar Transistor). On the one hand, transistors enable maximum operating safety due to components that can be switched off; on the other hand, the plant can continue to operate with slightly reduced power even if an IGBT module fails. At Otto Junker, medium-frequency crucible furnaces with capacities of up to 60 t and outputs of up to 28 MW are supplied with the operationally reliable IGBT technology. The furnaces are used, for example, for steel applications, DRI melting and as a CO2-free replacement for cupola furnaces.

Otto Junker has also further developed the patented laser-optical measuring system for monitoring crucible wear and the thermal load on the induction coil. At the trade show, comprehensive information will be provided on the proven OCP+ (Optical Coil Protection) system, which has now been made even more user-friendly.
