The ABP VIRTUAL TRAINING is an important part of the ABP VIRTUAL ACADEMY. This is where important actions, work steps and emergency measures can be planned – from any location and at any time, on a virtual twin of a system. Modules such as the „Bridging“ module can be used to train scenarios that would ideally not occur in real life – but which cannot be easily trained in real-life situations either. This makes it possible to virtually stage real conditions that would not be possible to create on the actual object for safety reasons. The virtual training courses are also a tool for training new employees. ABP‘s virtual training modules can be easily completed as a desktop application like a computer game or interactively in the room using special equipment.
The virtual training modules are developed by ABP‘s digitalization experts and are based on years of experience in the field, as well as on feedback from various ABP customers. As such, special training modules can also be developed for irregular maintenance and malfunctions that occur only infrequently. Individual scenarios just for the production environment of a single customer can also be developed. There are numerous advantages to virtual training. Because of the abstraction factor, there is never any danger for man or machine, and at the same time, working on the system is extremely realistic because of the interaction it provides. On the other hand, the virtual trainings are particularly efficient. Production operations are not restricted, there is no need for cost-intensive melting, and time can be saved thanks to the accelerated simulation. Since training can be conducted at any time in basically any location, you also save on travel expenses and unproductive employee time as a result of traveling.
ABP Virtual Training: With the „Bridging“ module, foundry employees can practice on a digital twin
A very striking example is the training to prevent bridging in the induction furnace of our foundry customers. When melting in the induction furnace, the charge material can form a solid blanket above the active coil because the electromagnetic field no longer couples there. This can interfere with the actual melting process by causing this part to get stuck and prevent the scrap from sliding into the active part of the coil. The potential consequence: This results in severe overheating of the melt in the lower crucible section, which loses contact with the scrap suspended above it. This overheating can attack and damage the furnace lining. Failure to detect this in time can result in furnace blowout or explosion due to overheating. All in all, this is a process that can have a massive impact on safety and operation and must be avoided at all costs. This is where training comes in: ABP Induction has developed a virtual training module specifically for the bridging phenomenon. It allows the scenario described to be simulated and then trained – on the digital twin of the system and thus not in a direct production environment, but in a highly practical manner while taking all safety-relevant aspects into account. The employee trains all work steps virtually and is also able to experience hazardous situations in this special training that are impossible to train in the physical environment – and, in the best case scenario, should not ever occur at all.
A workplace of extremes – this certainly is the case when working in a foundry where metals are processed at temperatures of more than 1,000 degrees. The very highest level of safety during processing is of course crucial here, but so is the quality of the product at the end of the process. Up to now, this process depended primarily on the respective expertise of the smelter.
This process is now digitally documented, analyzed and optimized by means of artificial intelligence with the „FoundryCloud“ from the start-up Zorc Technology. The „FoundryCloud“ is integrated directly into the ABP gateway and interacts seamlessly with the myABP platform. The Zorc solution, which was developed exclusively for foundries, represents the platform for predictive process control. Further digital business models in this environment are within close reach. The first platform of this kind has now been installed in Krefeld.
The Siempelkamp Foundry has been facing major challenges that impact the entire metal processing industry: Reduction of energy costs and CO2 emissions, the topic of sustainability in its three dimensions in general, and thus competitiveness in the long term. Siempelkamp decided to take a great leap that was unique in the industry and demanded a trailblazing sense of pioneering spirit on the part of all those involved. The modernization of its induction furnaces heralds the beginning of a digitization offensive the likes of which have never been seen before on this scale in the foundry sector. The digital control of the plant now enables higher-precision production with even lower waste.
ABP makes first complete digitalization of melting operation possible
Benefits range from lower power consumption to reduced costs and greater environmental protection. In addition, the foundry can now complete customer orders with much greater speed, efficiency, and manufacturing accuracy. Employees also benefit from the upgrade to their job description, they enjoy greater job security, and even safer workplaces. The transition to digital control is being carried out gradually in several installation and test phases, one of which involves ABP‘s PRODAPT® melting processor, and was completed by the end of 2021. The furnaces started their fully digitalized operation in January 2022.
Interfaces between systems and operating system
Why Siempelkamp has brought a classic system manufacturer on board with ABP Induction becomes quite clear when looking at the developments at the Dortmund-based company over the last few years: ABP has built up its very own digitalization division and today offers numerous digital services related to foundry operations – from virtual classrooms and virtual reality training to augmented reality support for maintenance and repair. Moreover, there are also components such as the controller by ABP Intelligence on the ABP gateway with the necessary interfaces to the operating system of the foundry. The myABP portal acts as the heart of the system and provides an overview of all relevant systems and processes – all elements from furnaces to scales to temperature measurements using lances are integrated, regardless of their manufacturer. With its data quality and transparency, it provides the foundation for a continuous optimization process.
With this, ABP has created the platform for the „FoundryCloud“ software solution, which Zorc Technology has developed specifically for foundries. This new software for monitoring metallurgical control and documentation stores the foundry‘s operating parameters and transmits experience- and AI-based suggestions to optimize production directly to the employees. Previously, each casting was primarily dependent on the specific knowledge of the melter, but now the melter is assisted by the new software. It monitors the processes in the induction furnace and documents the parameters. It uses the data to develop suggestions for optimizing the process and sends the suggestions to the relevant employee, who can then use them to make adjustments. In the process, the software uses existing data and, thanks to the integration of artificial intelligence, is constantly learning. In this way, the data pool becomes steadily larger and the quality of the casting process steadily better. As a result, costly corrections and even rejects can be prevented to the greatest possible extent. While 98 percent of the casting process is already firmly controlled, the digitalized system gives the Siempelkamp Foundry an additional increase in manufacturing excellence. The operating parameters that need to be monitored during a casting are highly complex and multifaceted: Loading, start and target temperature, process times, and last but not least the optimal use of energy – each factor plays a decisive role in the ultimate success of the process. As the digitized furnaces now collect, store and evaluate key data, artificial intelligence can be used to analyze and further process it.
Comparing data, recognizing patterns
Thanks to the resulting algorithms, data can be compared and recurring patterns detected. The result: The software is able to solve previously unknown problems with an ever-greater degree of precision and supports the employee at the furnace in controlling the processes proactively. The user can therefore dedicate his full attention to interpreting the data and adapting the melting process to it in the best possible way. This is a particularly valuable aid when new components and factors have to be included. However, the digitization of induction furnaces also shows how important the interaction between people and technology remains in the age of Industry 4.0: Employees and their expertise in terms of interpretation cannot be replaced in the process. The digital solution merely supports them in casting even faster, more efficiently, more correctly and more routinely.
Learning platform for training
The Krefeld-based company has opted for comprehensive training courses to familiarize its employees with the new technology. The aim is not to train the foundry mechanics as IT specialists, but to expand their metalworking skills to include the use of digital applications. The three cooperation partners are therefore also increasing the value and scope of the foundry profession profiles and making their companies more appealing to applicants. The topic of work safety will also be part of the virtual classroom training in the solution, which in addition to teaching the technological innovations has already won numerous awards. In addition to production support, the pool of data makes it possible to simulate crisis situations in a preventive manner, which employees can act out with the help of state-of-the-art VR technology. This therefore makes the foundry mechanic‘s workplace a little safer when dealing with the red-hot molten metal.
At the same time, the site‘s ecological footprint is significantly improved as a result of the lower energy and material consumption. After all, the central unit is responsible for two-thirds of the company‘s electricity consumption. More accurate processes and even less waste can help reduce CO2 emissions in this area. According to initial estimates, this could result in total CO2 savings of up to 1,000 metric tons per year. A look at the entire system also reveals a positive environmental aspect: The maintenance program that has been incorporated into the software solution, with its end-to-end condition control and monitoring, means that preventive maintenance can be carried out in a highly targeted manner. It thus makes a significant contribution to extending lifecycles. Transitioning to more energy-efficient processes also makes production more economical for the foundry. This represents a major competitive asset for a business in an energy-intensive sector. After all, energy costs at German foundries currently account for 25 percent of their gross value added. In view of the fact that electricity prices have nearly tripled in the past 15 years, this is an item in the budget that should definitely not be underestimated. The additional reduction in waste scrap also leads to savings in materials. The new platform technology will therefore also have a noticeable effect on the company‘s bottom line. And this with a comparatively low investment volume – in comparison to the entire furnace system. And this is yet a further point that will enable the company to set itself apart from its competitors.
