NON-METALLIC INCLUSIONS AND CLEAN STEEL
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 ...

Non-metallic inclusions in electroslag refined ingots
2010The 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 ...
