material wear in blast furnace crucibles
Design of Blast Furnace Crucibles by Means of the Nodal
The Nodal Wear Model (NWM) is used to explain and quantify the causes for the occurrence of different corrosion profiles observed in the hearth of blast furnaces during their campaign and as a consequence it is possible to use the NWM to define the most appropriate refractory materials for designing and constructing blast furnace crucibles.
