ATAS MetStar is an easy to use, adaptive metallurgical process control system for analyzing, stabilizing and optimizing the metallurgical production process. ATAS MetStar is the fundamental tool for a foundry to improve quality, control and increase stability of the metallurgical parameters. The result is reduced scrap rate, less energy consumption and a greener planet.
ATAS (Adaptive Thermal Analysis System) MetStar is a flexible metallurgical process control system for analyzing, stabilizing and optimizing the metallurgical production process. The system has been developed from a metallurgical point of view, based on years of foundry experience both from NovaCast’s own personnel but also customers’ day-to-day challenges. The system is used to create routines and rules for developing a lean production method.
The analyze phase consists of analyzing a number of physical samples of a specific alloy or melt quality and find the best practice. The stabilizing phase consists of extracting data from the analysis and defining the unique fingerprint for a specific desired quality to secure the best practice. The optimizing phase is the final stage of our process where fine tuning and improving the best practice takes place. This leads to a process with less variations and a stable quality and results in reduced scrap rate, less energy consumption and a greener planet.
ATAS MetStar predicts the possible risk for defects in the castings such as; micro shrinkage porosity, macro shrinkage porosity, chill tendency (cementite), inverse chill tendency, oxygen content and mechanical properties.
>> One of the latest news in ATAS MetStar version 10.3 (released on October 26, 2022) is Reaching eutectic morphology in ductile iron production with different thermal modulus (ACEL vs. Modulus)
The demands for defect free castings today are very high, therefore many our users rely on ATAS MetStar aid. Normally ATAS MetStar gives a good correlation between acquired thermal properties and ACEL (Active Carbon Equivalent evaluated from Liquidus temperature), if the castings have approximately the same thermal modulus (M~0,75 cm) as plain sand cups. The tricky part is to aim for correct ACEL target in the plain sand cup for final ductile iron to get eutectic morphology in the different size of casting (different modulus). This has been under development for many years, but now is finally ready to our users, which will greatly improve ATAS MetStar useability for different size ductile iron production.
