  1. Quick answers for Chemistry, Inoculation and Microstructure Presented by MeltLab Systems 2010 Thermal Analysis of Foundry Metals

  2. Molten metal is poured into a sampling cup containing a thermal couple The Process Takes about 30 seconds of operator time, results in 2 to 6 minutes

  3. Phase diagrams measure the transition points from liquid to solid, from one structure to another. The Theory Iron-Carbon phase diagram

  4. As simple or as complex as you like Includes all phase diagram information And alloy correction calculations Data Presentation

  5. Turn displayed items on or off Data Selection

  6. User controlled files • Connects with our GSPC system for • On the floor monitoring • SpectrometerLab to include results with Chemistry • Long term historical files for record keeping and, with GSPC, graphic analysis Data Storage

  7. Iron Chemistry Ductile Microstructure Grey Microstructure Aluminum 300 Series Steel & High Temperature Alloys Copper Alloys Other Metals – Sterling Silver Methods of analysis

  8. Higher precision to get 16 fold improvement Invented new data smoothing methods Researched TA for better understanding of data Redesigned instrument for the foundry environment Evangelized to try to get the word out Necessary Improvements

  9. Shielded wiring to prevent furnace power from getting into the measurement • Proper electrical grounding to provide a reference to measure from • Proper Metal Sampling • Hot enough that all alloys are dissolved (1400˚C) • If final metal, then fully inoculated/treated • Full sample cup Foundry Requirements

  10. The following slides are meant to show the capabilities of MeltLab. They show details that may be more complex than you would want to display to the melters. But they can be useful to the quality of the metal. Our philosophy is that it is better to have more than you need rather than to have less than you need. The graphs have been shrunk for this presentation. MeltLab Capabilities

  11. Iron Chemistry for grey & Ductile

  12. Iron Microstructure for Ductile

  13. Aluminum Microstructure

  14. Steel & High Temp Alloys

  15. Copper Alloys

  16. If you have any particular alloy you need to measure, MeltLab has the capability to: Measure any arrest point or phase change Based on phase diagram or chemical analysis, develop equations to convert arrest points into chemistry Measure and quantify the amounts of the different phases detected. Other Alloys

  17. Thermal analysis is now giving faster results than any lab can do Gives feedback in time to make corrections MeltLab is already two generations beyond what any other TA unit can do. Visit www.meltlab.com for more information on what can be done. Conclusion

  18. Presented by MeltLab Systems 2010 MeltLab Systems based in the United States of America is the inventor of the MeltLab system, Graphic Statistical Process Control and other software designed for foundries.
