TA 12.13 Thermal Analysis for Aluminum Melt Quality

Maintaining consistent aluminum melt quality is essential for achieving stable casting performance. TA 12.13 Thermal Analysis provides a practical solution for monitoring aluminum melt quality through the analysis of its solidification behavior.

The system evaluates the cooling curve of a molten aluminum sample to determine key indicators for grain refinement and modification. These results help foundries assess melt condition and make timely adjustments before casting.

How Does TA 12.13 Work?

TA 12.13 uses a monitoring system and sensor stand with a permanent thermocouple.

A molten aluminum sample is placed in a reusable stainless steel crucible. During solidification, the thermocouple records the cooling curve and displays the relevant temperature points in real time.

The system then analyzes the curve to determine Grain Refinement (GR) and Modification (M) values.

These parameters provide information about the expected microstructure and mechanical properties of the casting.

Monitor Grain Refinement and Modification

TA 12.13 helps evaluate the effectiveness of melt treatment elements such as:

• TiB for grain refinement
• Sr for modification
• Na for modification

Grain refinement describes the grain size, while modification represents the homogeneous distribution of silicon in the microstructure.

By monitoring these values, operators can identify changes in melt condition and adjust the treatment process when necessary.

Key Features of TA 12.13

TA 12.13 is designed for daily use in foundry environments and provides several features for practical melt monitoring:

• 12-inch industrial touchscreen
• Precise measurement with high sampling rate
• Digital data transmission
• Dynamic measuring frequency of 10/40 Hz
• Automatic identification of relevant curve points
• Reproducible calculation of grain refinement and modification
• Calculation and display of first and second derivatives
• Grain size determination according to ASTM E112-10
• Automatic detection of potential faulty measurements
• Thermocouple ageing and breakage control
• Automatic batch number assignment
• Customer-specific warning and blocking limits
• Relational database for measurement results

MeltBoard PC Software

TA 12.13 works with MeltBoard PC Software for data management and analysis.

The software allows users to:

• Display measurement results in tables and graphs
• Compare two or more cooling curves
• Analyze measurement data using filters
• Store reference curves for comparison
• Generate trend diagrams and histograms
• Archive measurement results
• Generate reports in HTML, CSV, and PDF
• Maintain quality assurance and traceability data

Multiple TA stations can also connect to a central database, allowing users to monitor operating status and manage measurement data across the network.

Designed for Aluminum Casting Alloys

TA 12.13 is designed to monitor typical aluminum casting alloys with approximately 5% to 13% silicon.

The system also supports established special alloys such as:

• AlZn10Si8Mg
• AlMg5
• AlCu4Ti

Customized alloys can also be accommodated on request.

From Melt Testing to Process Control

TA 12.13 turns thermal analysis into a practical melt quality control tool.

Instead of waiting for time-consuming microsection analysis, operators can use thermal analysis as a faster decision-making tool during daily production. The results can help evaluate melt treatment and identify when adjustments to grain refinement or modification may be required.

This can support:

• Better melt treatment control
• More consistent casting quality
• Reduced rejection
• Improved process reliability
• Better traceability of melt quality

TA 12.13 for Aluminum Foundries
