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 10.1 (released on May 27, 2020) is the Sample Comparison.
Using Sample Comparison to find out the effectiveness of an inoculant or total amount of oxygen in the molten iron. Taking a sample of a melt and analyzing the cooling curve will give you much important information about the state of the melt. When you compare two correlated samples, but with a known difference, you can gain even more knowledge. In the latest version of ATAS MetStar, you can in the production unit, open the Curve Comparison and compare two curves directly from any of the channels. Inside of curve comparison user can chose between different preexisting modes such as Inoculant, Gray/White, Total Oxygen or general. Or compare a sample from a channel with one you have recently taken. After the fact, you can go into the Curve Analyzer and compare samples there as well.
