Cleanliness determination and Inclusion Analysis in Steels with Bruker Elementals Spark Spectrometer Q8 MAGELLAN & MCI

The present production of steels shows demanding requirements for quality, especially the needs for homogeneity and cleanliness are increasing. The key to premium steel products are best cleanliness degrees and lowest levels of Oxygen.

The present production of steels shows demanding requirements for quality, especially the needs for homogeneity and cleanliness are increasing. The key to premium steel products are best cleanliness degrees and lowest levels of Oxygen.
The classic way to determine non-metallic inclusions is usually using metallographic microscope and scanning electron microscope with EDX analysis (SEM-EDX). These methods are slow and cost-intensive applications. Using optical emission spectroscopy with pulse discrimination analysis (OES-PDA) means fast and efficient determination of the cleanliness degree and oxygen level. During the melting process these quality indicators are available and allow the process control in real-time. In addition a fast quality check of the final product is one of the main advantages of this method.
For this purpose Bruker Elemental has developed the software package MCI, “Metal- Cleanliness-Inspection” for the spark spectrometer Q8 MAGELLAN. The MCI-Software evaluates on a statistical basis the sparks, which are caused by non-metallic inclusions.
The main features are the determination of:
- Total oxygen content
- Oxide and sulfide inclusions
- Grain size distribution of different oxide and sulfide types (e.g. alumina, Ca-aluminate, Mg-spinel)
- Cleanliness degree in correlation to reference methods (e.g. EN 10247, ASTM E45)
The right solution for this application is Q8 MAGELLAN, a sparc emission spectrometer setting new standards with respect to technology, reliability, flexibility, and handling. It is the first spectrometer worldwide that offers a previously unseen quality of analysis because of its unlimited combination possibilities of measurement parameters. It is the only vacuum spectrometer featuring channel-photomultipliers, digital plasma generator, unlimited single-spark- and time resolution and a heavy duty, low-maintenance spark stand with co-axial argon flow.
Q8 MAGELLAN is suitable for routine operation in both laboratory and production environments. Newly developed electronics, detectors, optical components and information technology ensure that Q8 MAGELLAN dramatically differs from the broad range of spectrometers on the market. The components were mated in such a way that unmatched performance can be guaranteed.
