A natural cooling of the slag tapped from an AOD (Argon Oxygen Decarburization) converter for stainless steel production may result in slag disintegration or dusting. The dusting is related
In the AOD process, the primary decarburization slag is reduced and adjusted to higher basicity for desulfurization and after this treatment tapped into a slag pot (single slag practice). In the case of demanding final sulfur target, the reduction slag can be tapped and an additional slag with higher basicity can be formed (2-slag practice).

In the steelmaking process, stainless steel waste passes through two furnaces. In the first so-called argon–oxygen decarburization (AOD) furnace, the first fusion of the materials is produced, and basically two parts are obtained: At the bottom of the bed is the concentrated liquid steel, and in its upper part, floating, a slag which contains fewer iron components and alloys, …

For the AOD slag, the va lues are often close to 2 and the C 2S is a predominant slag mineral, which can form sol id solution with CaF 2 [5]. Thus the C 2S in the AOD slag may associate with both the -C 2S-driven slag dusting and the F leaching. J. Savolainen et al. performed plant slag granulati on trails for a better control of F leaching from
