Abstract：The volume expansion of stainless steel argon oxygen decarburization （AOD） residue during the cooling process will cause efflorescence and dusting problem， which not only caused serious pollution to the environment， brought great harm to the human body， but also caused a waste of resources， therefore， it needs to reduce the efflorescence problem of stainless steel slag and to improve the utilization rate of stainless steel slag urgently. In the current study， the inhibitory effect of AOD stainless steel slag was studied by adding different modifiers. The result shows that both of the curing effect and curing rate are gradually increased with the increase of added content of B2O3 and P2O5， while the AOD slag has no obvious curing effect when adding CuO as modifier. Analyzing the reason of curing effect， it shows that added ions can be enriched on the grain boundary and dislocation of 2CaO·SiO2 when the radius of added ions is smaller than that of Si4+ such as B3+ and P5+， and this enrichment will reduce the defect free energy and the driving force to form[γ-2CaO·SiO2]. It also can inhibit the crystal nucleation and growth of[γ-2CaO·SiO2]. All of these effects can make 2CaO·SiO2 stabilized in the[β]phase， thereby inhibiting the dust of stainless steel slag.
