Presentation technical paper: "Process Control of Ductile Cast Iron by Means of Thermal Analysis”.

During the event, Joao Cunha and Craig Taylor successfully presented a technical paper titled: "Process Control of Ductile Cast Iron by Means of Thermal Analysis”. This presentation highlighted our innovative approach to ensuring the quality and consistency of ductile cast iron production through advanced thermal analysis techniques.

Key Takeaways:

• The production of high-quality ductile cast iron components is highly sensitive to key metallurgical parameters such as magnesium content and inoculation potential. If these variables are not properly controlled, casting defects like carbide formation, shrinkage, microporosity, and graphite degeneration can occur, compromising the integrity of the final product.
• Thermal analysis offers a powerful tool for gaining real-time insight into the condition of the molten metal. It enables rapid corrective actions to ensure the melt reaches optimal pouring conditions, thereby supporting a stable and efficient casting process while minimizing defects.
• Using the Meltcontrol Foundry thermal analysis software from Heraeus Electro-Nite, in combination with the Therm-O-Stack double-chamber cup, foundries can accurately assess the melt’s current state—including magnesium levels, nodularity, and inoculation potential. This data is then processed by the Foundry Navigator software, which provides precise recommendations for alloying additions (e.g., Mg, inoculants, carbon, FeSi, Cu, etc.) to maintain the melt within the desired process window.
• This integrated system serves as a comprehensive solution for metallurgical engineers and foundry operators, guiding them through the quality control process and ensuring consistent production of sound ductile iron castings.
