Secopta presents new LIBS system

At the Tube, Secopta presents its new LIBS system which, for the first time, enables fully automatic inline Positive Material Identification (PMI) testing of long steel products in black condition. With more than 99.9 percent reliability, the system identifies material whose chemical composition is not as specified and removes it from the production process. Thus, the system can be used, for example, to prevent that the wrong semi-finished products are selected for a downstream process.

For bright steel products, fully automatic Positive Material Identification (PMI) testing has already become an established process in many mills. With its FiberLIBS black bar system, Secopta now applies its range of inline LIBS systems for the first time also to black steel products. The laser-based system dramatically reduces the manual effort so far involved in material identification processes, “very often even making separate mechanical sample preparation unnecessary.”

Secopta has adapted the sample preparation system integrated in their analyzers to the needs of black steel testing. Surface contamination, such as scale, oil and other interfering factors, are removed fully automatically. This makes it possible for the very first time to analyze steel in black condition without having to grind the samples beforehand.

Given the rising demand for smaller production lots and the constantly growing number of steel grades, reliable material identification along the entire process chain becomes increasingly important in steel production.

Other fields where LIBS systems are used include steel bath and incoming scrap analyses, and PMI of steel billets before reheating. Secopta: In all these applications, LIBS ensures that no mix-up of material goes undetected and no products with wrong material properties are delivered to the customer. Tube / Halle 6 / J11
