The original AOD slag was collected from the refining workshop of a stainless steel manufacturer in China. Because the AOD slag was powdery and had a fine particle size, it can be sieved directly with a 200 -mesh standard sieve (<74 μm) to remove agglomerat es and inclusions. The AOD slag obtained by sieving was placed in a drying box and dried
