Steelmaking - Oxygen steelmaking

Oral

The cleanness of modern steels is of utmost importance as non-metallic inclusions can have detrimental effects on the mechanical properties of the finished product, as for example fatigue strength or notched impact toughness. Especially, hard NMI have a lower formability than the surrounding matrix, which can lead to crack initiation in the material during forming. Additionally, NMIs often...

Steelmaking - Oxygen steelmaking

Oral

High-Cr and Ti-bearing ferritic stainless steel (Ti-FSS) has superior corrosion resistance compared to other steel grades. The Ti-FSS requires not only high corrosion resistance and formability but also superior cleanliness of the cold rolled sheet. Specifically, the cleanliness of Ti-FSS has been improved through the vacuum oxygen decarburization (VOD) and the ladle treatment (LT) processes....

80. Evolution of non-metallic inclusions in non-oriented electrical steel: Industrial observations and laboratory test results

Steelmaking - Oxygen steelmaking

Oral

Non-oriented electrical steel is widely applied as core material for several electrical machines, such as generators or electric motors due to its great soft magnetic properties. Besides grain size, precipitates, defects and grain orientation, non-metallic inclusions (NMI) also have a decisive effect on the magnetic properties of non-oriented electrical steel. Inclusions not only inhibit grain...
