Abstract
In a method for treating slags or slag mixtures having iron oxide contents of >5 wt.-%, in particular steelworks slags, in which the steel slags optionally mixed with other slags are charged onto a metal bath, a steel bath having a carbon content of <1.5 wt.-%, preferably <0.5 wt.-%, is used as the metal bath and the steel bath, after the charging of the steel slags, is carburized to above 2.0 wt.-% C, preferably >2.5 wt.-% C, by introducing carbon or carbon carriers.
