Global Pig iron update, Sourcing options for pig iron moving forward, pig iron demand increasing due to mini Mills. The war in Ukraine and how it will effect the pig iron market for years to come.

Recent research outcome on AI/ML driven meta modeling for high-strength ductile iron sand castings to predict yield strength using historical data with detail chemistry will be presented. During this panel, the effects and influences of lesser-known elements will be discussed and demonstrated for potential impact on yield strength.

• Growth of EAF mill production
• How much new production is here and coming?
• How does this affect prime grades availability?
• Is the Quality of prime scrap changing for foundry consumption?

As clean scrap continues to become more difficult to source, the need to diversify scrap purchases in order to identify least cost charges that meet tighter customer specifications becomes more and more demanding. Today’s software can help simplify the mathematics required to optimize raw material purchases. By making the software fully capable of automatically interfacing with ERPs, company servers, spectrometers, electronic scales, bar codes and other interfaces, the technology continues to focus on minimizing operator interaction while reducing process variances.

Ductile iron casting design and manufacturing is a multi-variable complex process that often is found inadequate in spite of extensive experience, well controlled operation and a traditional trial & error approach to solve periodic shrinkage porosity and poor properties not meeting the requirements. A framework and methodology consisting of machine learning and AI tools, coupled with ICME (casting process simulation) will be presented to develop meta model predictors with uncertainty quantification using historical production data and selective DOE based data with an example. Application of such meta models applied in near real-time intelligent process control will be presented with positive outcomes. This approach is applicable to solve any such complex problems encountered in the foundry and machining operations.

Grinding castings has historically been a danger and bottle neck in the foundry. With today’s labor shortage, the difficulty in getting castings through finishing is greater than ever. These three presenters will discuss the challenges and improvements they have made to their facilities in the area of Finishing throughput and automation.
