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.
