Abstract

Due to operational conditions and locations, BOF suffers variations in important parameters whose effects on the liquid bath are usually neglected. The present paper investigated two aspects: inner BOF pressure and oxygen temperature in the stagnant reservoir. The results have shown that oxygen temperature changes properties like density and velocity but has small influence on jet penetration. The BOF inner pressure has significant influence on jet penetration and creates a new challenge regarding nozzles dimensions considering overexpanding and underexpading jets.
