Abstract

The blow-in of CSN blast furnace n°3 in 2006 is reported with a focuson a large solidified salamander that had to be tapped. Analyticaland finite element models have been created to predict the expansionphenomena. The predicted values are compared with the hearth shellstress and strain measurements executed during the blow-in.
