Training Courses & OTTO JUNKER Academy

Advantage through knowledge

Training courses

Specific training of personnel will improve the efficiency of your production process. Minor problems can be resolved by your operating personnel immediately.

Problems due to improper operation of your equipment are reduced. The training programs are tailor-made to suit our customers’ needs. 

Examples of typical training subjects:

  • Theory and layout of converter plants
  • JOKS process visualization system
  • Handling of hydraulic components
  • Operation and maintenance
  • Adjustments, troubleshooting
  • Physical and technical basics
  • Safety devices etc.

"Education is the most important investment in people"

Franz Cornelsen

Safety training by means of Virtual Reality (VR)

A practical training is carried out by means of models, demonstrations, Virtual Reality simulations and testing facilities in line with the motto “by practitioners for practitioners”.

"Training in a safe environment"

Without doubt, rectifying an earth fault is one of the most important tasks of the maintenance personnel in many industrial areas. An earth fault can not only cause major operational malfunctions but also jeopardize the safety of employees. For this reason, we place great importance on training courses which are carried out in a safe environment in order to make sure that your personnel is prepared for a potentially hazardous situation in the best possible way.

Our training includes the use of Virtual Reality (VR), a modern technology, which can simulate realistic situations without causing actual danger. This allows your personnel to get familiar with the challenges of an earth fault in a safe manner. VR can be used to generate realistic training situations to gain practical experience without risk for personnel or equipment. This promotes effective learning and offers the possibility to learn from mistakes.

Our training is carried out by experts with in-depth knowledge in the foundry industry. They make sure that the training is not just informative but also provides practical insights based on real experience.

It is our target to prepare your personnel as well as possible for the challenges in connection with earth faults and other safety-relevant situations. We are proud of offering training courses which take place in a safe environment while at the same time imparting a high level of reality and practical knowledge. For us, the safety of your personnel and the integrity of your operation come first.

Targets of the OTTO JUNKER Academy

The personal requirements with regard to planning, operation and maintenance of industrial furnaces in metallurgy have changed rapidly over the past couple of years - the processes have become more complex and the design and layout of the equipment more demanding.

In late 2014, we founded the OTTO JUNKER Academy in order to allow employees to meet these new demands with the aim of passing on knowledge and experience in planning and modernization as well as the operation, maintenance and repair of industrial furnaces.

Profitability, reliability, energy efficiency and safety take center stage in these seminars. A practical training is carried out by means of models, demonstrations and test facilities in line with the motto “by practitioners for practitioners”.

The offer of the OTTO JUNKER Academy is addressed to the managers and employees of the manufacturing, maintenance and investment planning departments and includes the further education of existing as well as the induction of new employees.


Practical education

In view of the different requirements and technological differences, we offer our seminars in two different categories, in German and English each.


Foundry equipment – furnaces for melting and pouring and 
Thermoprocessing plants – heat treatment equipment


Our seminars consist of individual modules which can be put together to an individual training program. We give recommendations to the employees of the specialized departments such as investment planning, maintenance and operation which of the individual modules to attend.

The events are organized by OTTO JUNKER GmbH and carried out by our experienced experts. From case to case, we also invite speakers who work in the field or from universities. 

The successful participation in Academy events is confirmed in the form of a certificate.
