Abstract

The blow-in of CSN blast furnace n°3 in 2006 is reported with a focus on a large solidified salamander that had to be tapped. Analytical and finite element models have been created to predict the expansion phenomena. The predicted values are compared with the hearth shell stress and strain measurements executed during the blow-in.
