METHOD FOR PRODUCING A MAINLY CRYSTALLINE SOLIDIFIED STEEL SLAG
The present invention relates to a method for producing a mainly crystalline solidified steel slag to produce solid steel slag, in particular a solid steel slag which can be used, after crushing, as aggregate in construction. In order to avoid or reduce the formation of dicalcium silicate, or in other words in order to stabilize the steel slag, the basicity of the steel slag which is separated from the molten steel is reduced to a relatively small extent and, in combination therewith, a sufficient amount of aluminium is provided in the steel slag. Use is thus made of a low basicity material such as glass, which is added in a relatively small amount to the liquid steel slag after it has been separated from the molten steel, and of at least one aluminium rich material which is added to the steel furnace and/or to the liquid steel slag which is tapped from the steel furnace.
