摘要

Spinel inclusions have for a long time been considered to be very harmful to castability and product quality. The following quotations demonstrate the general view on spinel inclusions: "The dirty word-Spinels!" "Spinel is known as one of the most harmful non-metallic inclusions in steel." "Catastrophic plugging of calcium-treated steels seems to correlate with the presence of spinel" "Spinel just like alumina inclusions deteriorates the final quality of steel products because it has a high melting point and exists as a C-type inclusion, which is not plastically deformed and evenly dispersed. It also induces nozzle clogging, which decreases productivity and process effectiveness". The review papers by Larry Frank give an excellent overview of the impact of non-metallic inclusions on castability. Spinel inclusions, are specifically singled out as being very harmful in terms of clogging at the caster and surface quality of the final product.
