Studies of effect of glass/silicon powder coatings on clogging behaviour of submerged entry nozzles when using REM alloyed stainless steels

Abstract: The internal surfaces of modern submerged entry nozzles (SENs) were coated with a glass/silicon powder layer to prevent SEN graphite oxidation during preheating. The effects of the interaction between the coating layer and the SEN base refractory materials on clogging were studied. The results indicated that penetration of the formed alkaline rich glaze into the alumina/graphite base refractory occurs during preheating. More specifically, the glaze reacts with graphite to form carbon monoxide gas. Thereafter, … Show more

“…Already stated [7], the temperature of the SEN should never be over 800°C after preheating. However, these high preheating temperatures enable an increase of the interaction between the refractory base material and the molten steel during casting [1]. Hence, it is of great importance to obtain knowledge about the SEN's behaviour during the preheating process.…”

“…This steel flow through the SEN can be disturbed by nonmetallic inclusions which accumulate on the SEN's internal surface and lead to clogging of the SEN. This in turn can result in halted production, production losses, impaired quality and therefore increased costs [1][2][3][4]. During steelmaking the molten steel has a temperature of around 1600°C and if the SEN is at room temperature before being put in contact with the steel there is a high risk for thermal shock and resulting damage of the refractory base material (RBM).…”
