Quick answers for Chemistry, Inoculation and Microstructure Presented by MeltLab Systems 2010
Molten metal is poured into a sampling cup containing a thermal couple Takes about 30 seconds of operator time, results in 2 to 6 minutes
Phase diagrams measure the transition points from liquid to solid, from one structure to another. Iron-Carbon phase diagram
As simple or as complex as you like Includes all phase diagram information And alloy correction calculations
Turn displayed items on or off
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
Iron Chemistry Ductile Microstructure Grey Microstructure Aluminum 300 Series Steel & High Temperature Alloys Copper Alloys Other Metals – Sterling Silver
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
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
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.
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.
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 for more information on what can be done.www.meltlab.com
