The capability of cooling staves is crucial for a long campaign life of blast furnaces (BF). Transient heat transfer analysis of blast furnace cooling staves made of copper, cast steel, and ductile cast iron are performed. Moreover, the temperature field variations of cooling staves according to different distributions of gas flow temperature are studied. A discussion of cooling staves made of the three different materials is given based on their performance during the transient heat transfer process. The results indicate that copper staves are suited for a long campaign life, as their performance is much better compared to cast steel and ductile cast iron staves especially during unsteady heat transfer. Moreover, the capacity of staves made of cast steel is better than that of ductile cast iron.
