SF trials continue to show that the MeltCup by MeltLab is the best for iron quality control. Your foundry will enjoy time and cost savings. Here’s our review :
Since 2016, we’ve been using the MeltCup with success. We’ve also published results from some of our trials to compare the performance of thermal analysis cups . Click the links below for results :
Figure 1 : QuickCup (left) and MeltCup (right) in action. Experiments showed that MeltCup is the best cup for iron thermal analysis.
MeltCup Quick Stats:
1) Virtually Zero Boiling = more accuracy and consistency
Figure 2 : The bottoms of four iron slugs taken from QuickCup samples, showing what appears to be gas related defects or boiling : Not good.
- Boiling removes carbon and silicon—MeltCup is more accurate;
- Boiling makes it harder to fill the cup—MeltCup is easy to fill ( figure 1 );
- Under-filled cups cause missing and skewed data—Being easy to
fill, MeltCup results are more consistent.
Figure 3 : The bottoms of four iron slugs of MeltCup samples. No boiling or gas related defect : Good.
2) Less volume = faster results, but not too fast! Because time is money—MeltCup saves both time and money
- Like Goldilocks, speed has to be just right—MeltCup balances
speed with accuracy.
3) Higher gauge wire/under no tension=more sensitivity and less failures
- Thinner wire >> less mass >> MeltCup has faster response/more sensitivity;
- No tension >> MeltCup has lower thermocouple failure rate under high temps.
4) Made in smaller batches >> MeltCup is customizable for other applications: Did you know…?
- MeltCup can be used to measure Pearlite;
- MeltCup can be used for checking chemistry in treated Ductile Iron (Final Iron);
- MeltCup can be used to evaluate Gray and Ductile microstructure;
- MeltCup can be used to control inoculation levels in DI.
