Alumina increases the proportion of high melting phases in the FeO lean slag. The possible effects of alumina on carburization and wettability are explored with the help of literature, one possibility is that alumina decreases the wettability of slag with iron shell, hence increases the degree of carburization causing early melting of iron shells.
