Autoradiographic Investigations of Endogenic Non-Metallic Inclusions
Isotopenpraxis Isotopes in Environmental and Health Studies, 1987The quantitative autoradiography of “point” sources, i.e. the sources of diameters between 5 … 100 μm, has enabled investigations of insulated non-metallic inclusions. Several heats were made in an induction furnace. ST-5 steel samples were deoxidated by use of complex deoxidizers Al + Ce contained various amounts of cerium with the radioisotopes 141 ...

Advancing Analysis of Non-Metallic Inclusion Datasets
2022Non-metallic inclusions play a major role in defining the properties of steel and their examination has been greatly aided by automated scanning electron microscopes (SEM) coupled with energy dispersive x-ray spectroscopy (EDS). The output of SEM/EDS analysis generates a great deal of data that has not been utilized. The current work exploits this data

Surface modelling of crystalline non-metallic inclusions
Journal of Non-Crystalline Solids, 2001Abstract Non-metallic inclusions such as corundum and spinel-type compounds are crystalline at steelmaking temperatures. The crystal structure and the configuration of the atoms at the crystal surfaces affect the surface related energies and thus the growth forms of the inclusions near equilibrium.

Evolution of Non-metallic Inclusions in Si-Killed Stainless Steelmaking
Metallurgical and Materials Transactions B, 2021The evolution of non-metallic inclusions (> 10 μm) for the Si-killed stainless steelmaking process is studied. The effects of the slag basicity in the AOD (argon oxygen decarburization) process, Ca treatment, refractory in the casting ladle, impurities (Ti, Al) in scraps and tapping temperature in the AOD process on the evolution of the non-metallic ...

Non-metallic inclusion entrapment by slags: laboratory investigation
Ironmaking & Steelmaking, 2003AbstractNon-metallic inclusions that originate from secondary metallurgy treatments may provoke nozzle clogging during continuous casting and lead more or less directly to surface defects on final products. The amount of these non-metallic inclusions (oxides or nitride) in the solid or liquid steel is governed by the steelmaking practice and in ...

Non-metallic inclusions in electroslag refined ingots
1983The objective of this research was to investigate how non-metallic inclusions (inclusions) are physically and chemically transformed, removed and controlled from electrodes to the final ESR-product. Several 1020, 4340 and rotor (Ni-Mo-V) steel electrodes were refined by two ESR-units (7.5 mm and 200 mm in mould diameter) under different slag systems ...

NON-METALLIC INCLUSIONS AND CLEAN STEEL
La Metallurgia Italiana, 2008The source, the removal and the mechanical consequences of the non-metallic inclusions depends on their types and on their engineering. The chemical composition of the non-metallic inclusions and their volume fraction are determined by the management of the different steps involved in the production process: melting, refining and casting operation ...
