| description | The invention belongs to the technical field of steel slag production and application, and discloses a steel slag treatment technology. The steel slag treatment technology comprises the following steps that: 1) pretreatment is performed on steel slag, wherein the pretreatment involves hot splashing treatment and piling braising; and (2) steel slag obtained after pretreatment in the step (1) is screened after being subjected to three-stage crushing, materials with the particle size smaller than or equal to 8 mm are directly subjected to multi-stage magnetic separation, magnetic substances are final product steel fine powder, non-magnetic substances are final product tailings, materials with the particle size larger than 8 mm enter a rod mill to be crushed again, the crushed materials are screened again, the materials with the particle size larger than 8 mm are sorted through a magnetic separator, magnetic substances are final product particle steel, and non-magnetic substances circularly enter the rod mill.
