Continuous Aluminum Quality with the Liquid Metal Cleanliness Analyzer LiMCA CM

The LiMCA system provides total density and granulometric information on the inclusion content of aluminum melts, in real time, based on a user-independent and objective method. It is appropriate for applications in quality assurance, process control, and process development.

The total concentration and size distribution are displayed in real time on the computer screen.

It is easy to determine the impact of alloying practice, furnace preparation, settling time, feedstock mix, and similar parameters on melt cleanliness. The effects of routine casting practices (metal level control, turbulence in the metal distributor) are directly observed as they take place.


ABB’s LiMCA CM is the model for continuous measurement at a fixed location. The LiMCA CM has been designed for reliability and robustness and can run continuously in the harsh environment of aluminum plants, requiring minimal scheduled maintenance.

The LiMCA CM allows for real-time, in-line measurements.

Inclusion monitoring is tracked every minute, providing a continuous in depth view of process quality.
